What coins equal to 0.88 with nine coins?

Answer 1

There's more than one possibility using modern coins:

> 2 quarters, 3 dimes, 1 nickel, and 3 pennies

> 1 half, 2 dimes, 3 nickels, and 3 pennies

If you want to impress your teacher tell them that you're using coins from the 1870s. See how many combinations you can come up with if you also use these 3 now-obsolete denominations that were in circulation back then: 2¢, 3¢, and 20¢.
