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?

A. 6

B. 12

C. 20

D. 24

E. 120

Answer: AExplanation: 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.
