In Loudland, where everyone makes as much noise as possible, the inhabitants have three coins in their currency: a 3 honk, 4 honk, and 7 honk. One inhabitant recently bought a 2000 Watt stereo system for 63 honks using 15 coins, however, because of the noise going on around him, he couldn't recall how many of each coin type he had used. The three numbers of coins were each from 1 to 9 inclusive and no two numbers were the same. How many of each had he used?
