Cheryl gave Brenda 7 coins worth .92 cents. Two coins were quarters. What were the other 5 coins?

Probably there are equations that can be set up but you can also do it by logic.
2 coins are 0.25 = 50 cents. That leaves 9250 = 42 cents and 5 coins to go.
The only way to get 2 cents is to have 2 pennies. That leaves 40 cents and 3 coins to go.
The only way to get 40 cents with 3 coins is 1 quarter, 1 dime, and 1 nickel.
So you have 3 quarters = 75 cents.
2 pennies = 2 cents.
1 dime = 10 cents.
1 nickel = 5 cents.
92 cents total and 7 coins.
