Monique has $2.00 in change in her purse. if she has an equal number of nickels, dimes, and quarters, how many of
each does she have?

Let the number of coins = X

A nickel is 0.05

A dime is 0.10

A quarter is 0.25

Set up an equation to add all the coins together to equal the total she has:

0.05x + 0.10x + 0.25x = 2.00

Simplify:

0.40x = 2.00

Divide both sides by 0.40

x = 2.00 / 0.40

x = 5

Check:

Nickels = 0.50 x 5 = 0.25

Dimes = 0.10 x 5 = 0.50

Quarters = 0.25 x 5 = 1.25

0.25 + 0.50 + 1.25 = 2.00

She has 5 of each coin.

a. she will receive a refund of $278.
