Question

A collection of 109 coins is made up of quarters, dimes, and nickels. There are 7 fewer dimes than quarters and 3 less than five times as many nickels as dimes. Find the amount of the collection.

Answer 1

The amount of collection is $ 10.60

Explanation:

If the number of quarters is x, the equation is x+(x-7)+(5(x-7)-3)=109.

7x-45=109

7x=154

x=22
