Nancy and Kerry have the same number of coins.
Nancy has only dimes and Kerry has only quarters.
If Kerry has $3 more than Nancy, how much does she have?
:
.25q - .10d = 3.00
:
d = q, therefore we can replace d with q
.25q - .10q = = 3
.15q = 3
q = 3/.15
q = 20 quarters, and of course 20 dimes

Check this
.25(20) - .10(20) =
5.00 - 2.00 = 3.00
