Alternate Solution

Randolf paid $12 per class for every 45-minute class.

Hence, in one class, the difference between amount spent and time spent = 45 – 12 = 33

Therefore, to create a difference of 132, he must have attended  \frac{132}{33}  = 4 classes

Hence, the correct answer is option B.

Answer: B

DavidTutorexamPAL · Answer

Instead of trying to create equations and calculate, which can be confusing, we'll just use the answers.
This is an Alternative approach.

Starting with the median - say Randolf attended (C) = 5 classes.
Then he spent 5 * 45 = 200 + 25 = 225 minutes and paid 5 * 12 = 60 dollars. 225 - 60 = 165: too much!
(C) is eliminated as are the larger (D) and (E).
(B): 4*45 = 160 + 20 = 180 and 4*12 = 48. 180 - 48 = 180 - 50 + 2 = 132. Yes!

(B) is our answer.

Solution

Given:  
 • Yoga for Life offers 45-minute classes at $12 per class
• Number of minutes Randolf spent during yoga this month was 132 greater than the number of dollars he paid

To find:  
 • Number of classes that Randolf attended this month

Approach and Working:   
If we assume that number of classes attended by Randolf is x, then
 • Number of dollars Randolf paid = 12x
• Number of minutes Randolf spent = 12x + 132

As every class takes 45 minutes, we can say
 • 45x = 12x + 132
Or, 33x = 132
Or, x = 4

Hence, the correct answer is option B.

Answer: B

(E) 8

Let he attended X classes.Therefore total number of minutes he attended = 45*X minutes, and total money spent is 12*X
From Question, it's given that 12X -132= 45X
=>33X= 132
=> X=4
 B is the answer.

sumitkrocks · Answer

(x+132)/x=45/12..where x is $ spent ...x=48 ...number of classes =48/12=4 hence, Option B is the Answer

KSBGC · Answer

Let the total number of classes Randlof attended be x

we can translate the question to form an equation:

45x=12x+132....................paying a careful attention on the second line of the question. Minutes is the base to form this equation. 
33x=132
x=4.

Thus the Best answer is B.

Back solving can also be used to solve this one quickly.

ScottTargetTestPrep · Answer

We can let n = the number of classes Randolf attended. Thus, the number of minutes he spent is 45n, and the number of dollars he paid is 12n. We can create the equation:

45n = 12n + 132

33n = 132

n = 4

Answer: B

jp28 · Answer

Total Minutes
M = 45x
Total Cost
C = 12x

45x = 12x + 132
33x = 132
x = 4

Ans  B
