If a collection of coins contains 15% pennies, 20% nickels, and 10% dimes,
how many of each kind of coin does the collection have if it has a total of 200 coins?
:
All the coins have to be 100%, therefore
100 - 15 - 20 - 10 = 55% must be quarters
:
.15(200) = 30 pennies
.20(200) = 40 nickels
.10(200) = 20 dimes
.55(200) = 110 quarters
------------------------
total coins: 200
