Mr. Cepluch has some nickels and dimes in his pocket. He has a total of 20 coins, and the coins add up to $1.35. How many nickels and dimes are jingling around in Mr. Cepluch’s pocket?

Answer 1

To answer this question you need to set up a system of equations.

The question tells us what the 2 equations should be:

Nickels + Dimes = 20 coins

Nickels + Dimes = $1.35

Let n = the number of nickels

Let d = the number of dimes

n + d = 20

0.05n + 0.10d = 1.35

Using the elimination method, solve for one of the variables. Then plug the answer into one of the equations, to solve for the second variable.
