How many dimes are in the coin bank?

Answer 1

38 dimes
13 dimes
23 dimes
none of the above

Answer 2

13?

Answer 3

Not sure how you would figure this out without answers, but with the answers we know

38 doesnt equal 23
13 * 10 + ( (23-13) * 25) = 1.30 + 2.50 = 3.80 **
23*10 doesn't equal 2.30 and there are no quarters.

Its 13 dimes
