Question 659025
try 4 quarters - not enough coins
try 10 dimes - not enough coins
try 20 nickels - not enough coins
try 100 pennies - too many coins
try 19 nickels and 5 pennies = 24 coins - not enough
try 18 nickels and 10 pennies = 28 coins - too many
try 16 nickels and 1 dime and 10 pennies = 27 coins - too many
try 14 nickels and 2 dimes and 10 pennies = 26 coins - too many
try 12 nickels and 3 dimes and 10 pennies = 25 coins - should be just right.
you wind up with 12 nickels and 3 dimes and 10 pennies for a total of 25 coins with a total value of .60 + .30 + .10 = $1.00
the answer i came up with is:
12 nickels = .60
3 dimes = .30
10 pennies = .10
.60 + .30 + .10 = $1.00
