$20.00-$19.35=0.65
You must do a guess and check!
0.65 cents is his change
He could have gotten:
2 Quarters (50 cents)=(2x25) Because there are two quarters and each are 25 cents
1 Dime (10 cents)=(1x10) because there is one dime and they are 10 cents
5 Pennies (5 cents)=(1x5) because pennies are 5 pennies and they are 1 cent a piece
CHECK
5+2+1 =8
8=8
So we have the correct number of coins
(2x25) + (1x10) + (5x1) =65
50+10+5=65
65=65
So we have the correct amount of change in cents

Step one:
12h-7=7h+18
12h-7h-7+7=7h-7h+18+7 Additive inverse
5h=25
Step two:
5h=25
5/5h=25/5 Multiplicative inverse
h=5
