SunnySpa is starting up a medical spa, offering dermatological and

For Question 3, 2nd sub question: doesn't the healing process for sunburns is peeling off the damaged skin cells and generate a new layer of skin? and the cream that has retinol helps to create a new layer of skin.

For Q1:

(K means thousands below)
given,
m= 10k
16i + 2f = 10K

=> 2f + 17i > 10K [Okay, so greater than rent] A ⛔️


But for the second claim,

all we know from the [16i + 2f = 10K] is that 8i + f = 5k
We can't say anything for 7i + 50m [= 7i + 5K] [How did we conclude that this can be determined to be less/more than 10K] Sajjad1994

­
Sure, 
For Option 2: 
Using the terms you defined:
16i + 2f = 10k
8i + 2f = 5k

So, 7i <5k. (1)

For 
100m = 10k
So, 50m = 5k,

7i + 50m < 10k hence yes.

For Option 3:
The student needs it in a week.
All treatments are monthly. So Business revenue will be less that 10k, since treatments don't qualify
 

DhruvBadaya
can you please explain the second part of the first question.
Also isn't cost of 100 microderma is equivalent to 10k?

­This is what I thought too. Can any expert help? MartyMurray , GMATCoachBen

What's the OE for 3rd part of Q3.

High school senior is hoping to have a glowing face with a fresh new layer of skin in time for prom next week.

Is it Microdermabrasion or acne creams?­

The timeline for improvement in case of Microdermabrasion is 1 month, and for acne creams it is for acne, and Ques doesn't state that the senior is having acne

Question 1.

­1. For each of the following combination of patients, select Yes if, based on the information provided, the business revenue generated can be shown to be less than the cost to rent the medical spa for the first month. Otherwise, select No

First month rent = cost of 16 Isolaz treatments + 2 Fraxel treatment packages,
or
First month rent = the cost of 100 Microdermabrasion treatments.

2 patients want treatment for deep pitted scars and 17 patients want to try laser to reduce the oil coming from their sebaceous glands.

For deep pitted scars, Fraxel is used. For reducing the oil coming from their sebaceous glands, Isolaz is used.
So we have 17 Isolaz + 2 Fraxel. This revenue is more than the first month rent.

Select: NO

7 patients want red laser treatment and 50 patients want microdermabrasions.

First month rent = the cost of 100 Microdermabrasion treatments
So with 50, half the rent is sorted. For the other half, we need 8 Isolaz + 1 Fraxel

Red laser treatment is Isolaz. We have 7 Isolaz only. Not sufficient.

Select: YES

High school senior is hoping to have a glowing face with a fresh new layer of skin in time for prom next week.

Though this option doesn't make much sense in this question, even if she comes for a procedure, she alone cannot bring in the month's total revenue within a week.

Select: YES

Question 2.

2. Which of the following statements can be inferred from the information provided in the three passage tabs?

A dirty face is the root cause for acne.

No. This is what we know:

During her adolescence, Pam began developing chronic acne. At first, she would wash her face everyday - some of her classmates suggested she had acne because her face was not clean. She did notice her face got very oily once adolescence began. So she started washing her face 3 times a day with a cleanser. Yet, her acne persisted...
also
Acne-creams: daily use, the most common creams include 2-5% benzoyl peroxide that attack facial bacteria

So cleaning her skin did not improve her case. So we cannot infer that dirty face is the root cause of acne from the passage. Also acne creams do kill facial bacteria but are they targeting the root cause of acne with that, I cannot say.

Excessive collagen production is a root cause for acne.

No. This is what we know:
Fraxel: once per month for 2-6 sessions, a more intense procedure that uses a laser to treat acne scars by stimulating collagen production deep below the skin.

Collagen production actually reduces acne scars.

A patient who is no longer breaking out with acne can still appear to have acne because of acne marks and scars that have been left behind by prior acne breakouts.

This is what we know:
Some of them helped but she was still getting a lot of acne - worse, some of the older acne was creating hyperpigmented dark spots on her face and leaving acne marks and scars.

We know that the situation isn't better if acne marks and scars are left behind. But does the person appear to have acne or just hyperpigmentation, I don't know. This isn't great, frankly, but it is the only viable option because the rest are far worse.

A combination of Isolaz, Fraxel, Microdermabrasion, and acne creams will cure Pam's case of acne.

No. we know that those are offered solutions. Will they work for Pam, we cannot say.

A blue laser that treats surface level bacteria can get rid of acne in Pam's case.

No blue laser mentioned.

Answer (C)

Question 3.

­3. For each of the following patients, select Yes if, based on the spa's assumptions, an appropriate treatment option exists in its product offering. Otherwise, select No.

Wedding bride wants to get rid of some acne scars on her face a few months before her wedding.

For acne scars, there is Fraxel. It takes a few months and the bride has a few months.
Select: YES

High school teenager got sun-burned while staying out in the sun too long without sunscreen.

There is nothing we know that treats sun-burn. The top or even the lower layer of the skin get burned. Is it treated? Is it removed? We have no idea. No treatment discussed talks about sun burn treatment.

Select: NO

High school senior is hoping to have a glowing face with a fresh new layer of skin in time for prom next week.

We have Microdermabrasion and acne creams for new layer of skin. Both can be used for next week.

Select: YES­

For the third part, how do we know the treatments mentioned for a new layer of skin will take a week or less? Isn't it possible that it takes more than a week? Nothing related to it is mentioned in the passage.

Microdermabrasion is given to be a regular once in a month service to reveal new skin. The process itself cuts the dead skin and reveals new skin. There is no mention of it requiring 10 days or so. The acne creams mentioned applied daily also lead to new skin.
So as far as we can tell from the given info, there are options available for the senior. Both give new layer of skin and there is no reason to believe that they will not work in a week.
