For this case, the first thing to do is define variables.
We have then:
- <em>x: number of nickels
</em>
- <em>y: number of dimes
</em>
- <em>z: number of quarters
</em>
We write now the system of equations:
Then rewriting the equations we have:
Then, substituting values we have:
Finally:
Answer:
19 nickels
14 dimes
7 quarters
