Answer:
6 quarters and 34 dimes
Step-by-step explanation:
Because we know there are 40 coins total, there must be 40-6, or 34, dimes. To verify that answer, 34 dimes is $3.40 and 6 quarters is $1.50. Adding those two values together produces $4.90, which means our answer of 6 quarters and 34 dimes is correct.
