I need to use quarters, dimes, nickles and pennies to make the following:
$1.53 in 12 coins $2.53 in 20
$2.32 in 15 coins $2.00 in 22
$1.45 in 10 coins
$1.76 in 16 coins
$0.85 in 11 coins
$1.01 in 12 coins
$1.29 in 15 coins

so, what ideas do you have?
$1.45 in 10:
3 quarters makes .75, so we need .70 in 7 coins. That means
3 quarters and 7 dimes
try the others. 
Carleen has three quarters, four dimes,and three nickels. Spends 55cent. How much mony does she have left
