Example:
Jack has $3.20 in nickels, dimes, and quarters. If there are equal number of nickels as dimes as quarters, how many of each coin are there? Solution:
Let 'n' be the number of nickels and 'd' be the number of dimes and 'q' be the number of quarters
n = d = q
5n + 10d + 25q = 320
5n + 10n + 25n = 320
40n = 320
n = 8
Therefore n = 8, d = 8 and q = 8 Directions: Solve the following word problems.
