Question

There are only nickels dimes and quarters in a bag. total value of coins is 3.75. if there are twice as many dimes as nickles, and 9 less dimes, how many of each coin are there.

Answer 1

Explanation:

Let x represent nickel

Then dimes be 2x and 2x-9

Quarter is 0.25

Total in the bag

x+2x+2x-9+0.25=3.75

Solve for x

5x=3.75+9-0.25

5x=12.5

x=2.5
