Step-by-step explanation:
We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...
0.10d + 0.25(23 -d) = 4.70
-0.15d + 5.75 = 4.70
1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides
7 = d . . . . . . . . . . . . . . divide by 0.15
There were 7 dimes in the change purse.
