2/5 of Amy's money was 3/4 of Ben's money. When Ben have Amy $28, both of them would have the same amount of money. How much did Amy have at first?

Assuming you mean when Ben takes 28 from Amy they have the same amount of money:

2a/5=3b/4

8a=15b

b+28=A-28

a=b+56

a=15b/8

15b/8=b+56

15b=8b+448

7b=448

b=64

64+56=$\boxed{\$120}$
