Question

Which equation best describes the relationship between the amount of money a in a bag of quarters and the number of quarters q?

A.
a = 0.25 + q

B.
q = 0.25 + a

C.
q = 0.25a

D.
a = 0.25q

Answer 1

I believe it's D. The amount of money in the bag depends on how many quarters you have; therefore you would multiply the amount of quarters by their value (.25) to get the total amount of money.
