Answer:
8 dimes and 17 nickels
Explanation:
First, we assume all of his coins are nickels. $0.05 * 25 will be $1.25. 165 - 125 is 40, and the money difference of a dime and a nickel is $0.05, so Ralph has 8 dimes and 17 nickels. We can check it by doing (8x10) + (17x5). 80 plus 85 is 165, therefore we can confirm our answer is true.
