Question

Your coin collection totals $24. You have an equal number of nickels, quarters, and half-dollars. How many coins do you have?

Please show your work.

Answer 1

90 coins

Explanation:

Nickels = .05

Quarters = .25

half dollars = .50

Since you have an equal number of them, call that x

.05x+.25x+.50x = 24

Combine like terms

.80x = 24

Divide by .8

.80x/.8 = 24/.8

x =30

You have 30 nickes, 30 quarters and 30 half dollars

The total number of coins is

30+30+30 = 90 coins
