The choices of answers are:

a) 21

b) 28

c) 35

d) 42

e) 63

I figured out that the answer is 35, but I did it by subtracting each of the possible answers by 7 and then multiplying that answer by 5/4.

This is what I did to get my final answer using 35: 35 - 7 = 28; 5/4 X 28/1 = 140/4 which equals 35.

Now, I know there must be a simplier way to get that answer.

Can you show me step by step? Thanks.

B= 5/4 * G = 5G/4

5G/4-7=G

5G-28=4G

G=28

B=28+7=35

G=28
