Five percent of a certain grass seed is timothy. If the amount of the mixture needed to plant one acre contains 2 pounds of timothy, how many acres can be planted with 240 pounds of the seed mixture?

Amount of timothy needed for one acre is 2 pounds.
So the amount of grass seed needed for one acre is 
= 2 (100/5) = 40 pounds

So the no.of acres that can be planted with 240 pounds is
= 240/40 = 6

The answer is A.

gater · Answer

My backwards math:

1% of 240 is 2.4 pounds
2.4+2.4+2.4+2.4+2.4=12 pounds

12pounds of timothy/2 pounds needed per acre=6 acres

AtifS · Answer

Answer: A 
 Explanation:  Let's suppose Grass Seed=G, and Timothy=T. 
And, we know that 5 percent of G is T (or T is 5 percent of G)
-->  T= \frac{5}{100} * G =\frac{1}{20} * G = \frac{G}{20} , and  G= 240 , so -->  T = \frac{240}{20} = 12  pounds.

We need  2  pounds of T for  1  Acre
==>  1  pound of T for  \frac{1}{2}  Acres
==>  12  pounds of T for  12*1/2  Acre -->  6  Acres (Answer)
So, we can plant 6 Acres with 240 pounds of seed mixture (in other words with 12 pounds of Timothy).
Hence, answer is A.

KarishmaB · Answer

Timothy - 5; Total Grass seed - 100; which is same as  Timothy - 1; Total Grass seed - 20;

For 1 acre;  Timothy - 2; so Total Grass seed - 40  (From above)
For ? acre;  Total Grass seed - 240 
Since 240 is 6*40, we can plant 1*6 acres.
Answer (A).

yezz · Answer

2 pounds ............5%
x pounds..............100%

x = 40 pounds for one acre thus acres = 240/40 = 6

BrentGMATPrepNow · Answer

We have 240 pounds of the seed mixture, and 5% of the mixture is timothy. 
So: TOTAL weight of timothy = 5% of 240 pounds 
=  12  pounds

So, we there are 12 pounds of timothy in the mixture, and  2  pounds of timothy is needed for  1  acre
This means  4  pounds of timothy is needed for  2  acres
And  6  pounds of timothy is needed for  3  acres
And  12  pounds of timothy is needed for  6  acres

Answer: A

JeffTargetTestPrep · Answer

5% of the total seed mixture n contains 2 pounds of timothy, so we have:

0.05n = 2

n = 2/0.05 = 200/5 = 40 pounds of mixture

We can create a proportion in which a = the number of acres that can be planted with 240 pounds of the seed mixture:

40/1 = 240/a

40a = 240

a = 6

Alternate Solution:

We note that there are 240 x 5% = 240 x 0.05 = 12 pounds of timothy in 240 pounds of seed mixture. Since one acre needs to contain 2 pounds of timothy, we can plant 12/2 = 6 acres with 240 pounds of seed mixture.

Answer: A

zishu912 · Answer

Given 240 pounds of seed mixtures

5 % 240 = 12 pounds of timothy is in 240 pounds of grass

2 pounds of timothy is enough for one acre, hence 12 pounds of timothy is enough for 6 acres

mm229966 · Answer

original mix is X pounds and 2 pounds of it is 5%; So the mix is 40 pounds in total;
now if we divide 240/40 we get 6 acres

ob184 · Answer

Is my approach is wrong?

240x5/100=12 (as 240 pounds will have 5% timothy)
1 Acre = 2 pounds of timothy so, 12/2 = 6 Acres

Imrane · Answer

My strategy:

1. It is obvious that the 25p bag is the least expensive per pound option. So customer will unquestionably buy the first 50 bags, by buying 25p + 25p ...

2. Now what is the least expensive option for the customer (knowing that he must buy at least 65 p) 2 possible options:
i. he buys a bag of 10 pounds + a bag of 5 pounds
ii. he buys one more bag of 25 pounds 
comparing the price of 10p + 5p vs 25p bag we see that it is less expensive to use strategy ii

so the customer will buy 3 bags of 25 pounds. 32. 25  per bag. No need to compute we know that answer must end with .75 => answer B

sherlocked221B · Answer

We are told:
 
  5%  of the seed mixture is  timothy . 
 It takes  2 pounds of timothy  to plant  1 acre . 
 We have  240 pounds  of the  total seed mixture . 
 We need to find  how many acres  can be planted with this mixture.

Since 5% of the mix is timothy:

Timothy= 5 percent of 240 = 0.05 * 240=12 pounds

Each acre requires 2 pounds of timothy

Therefore,

Acres= 12 pounds of timothy / 2 pounds per acre =  6 acres
