If the carrier had 7 more dimes, he would have equal numbers of dimes and quarters, and twice as many nickels. His total amount would be

... $4.25 + 0.70 = $4.95.

Each group of 2 nickes, 1 quarter, and 1 dime total $0.45, so the carrier would have $4.95/0.45 = 11 such groups.

The carrier has 11 quarters, 22 nickels, and 4 dimes.
