Question

Simone paid $5.25 for 3 pounds of apples. Which equation represents the cost, in dollars, C, of buying a pounds of apples?
C = 1.75a
C = 2.25a
C = 1.75 + a
C = 2.25 + a
Explain whatever the answer is.

Answer 1

I believe it is the first once because if a means the amount of apples and $1.75 is the amount paid for 1 apple, this answer would be correct.
