Problema Solution
A wallet contains the same number of pennies, nickels, and dimes. The coins total $1.44. How many of each type of coin does the wallet contain?
Answer provided by our tutors
let
x = the number of dimes = number of pennies = number of nickles
1 penny = $0.01
1 nickle = $0.05
1 dime = $0.1
the coins total $1.44
0.01x + 0.05x + 0.1x = 1.44
by solving the equation we find
x = 9
there are 9 of each coin in the wallet.
