Question

Roberta is thinking about joining the food co-op store. If she pays $10.00 to join, she will get 10% off on all groceries she buys there. how much must she buy before her savings equal her membership fee?

Answer 1

10% of G (groceries bought) = 10
.10G = 10
G = 10/.10
G = 100

check...
.10 x 100 = 10
10 = 10 (correct)

ANSWER : Roberta would have to spend $ 100 on groceries to make her savings equal to her $10 membership fee.
