Step-by-step explanation:

A piggy bank contains the same number of nickels, dimes and quarters

Let x = the number of nickels

Let x = the number of dimes

Let x = the number of quarters

The total amount of money is 3.20

.05x + .10x + .25x = 3.20

Combine like terms

.4x = 3.20

Divide by .4 on each side

.4x /.4 = 3.20 /.4

x = 8

There are 8 nickel, 8 dimes, and 8 quarters
