Question

Answer 1

4 Dimes

9 Nickels

Explanation:

I did guess and check (if you have an equation leave a comment or answer!)

So I did kept playing with the numbers making them go down until I could subtract the number of coins and divide to get the rest:

85-40 (4 dimes)=45

45/5=9 nickels

4+9=13

I hope this helps!
