Answer:

3 movies and 15 commercials

Explanation:

1 movies is equal to $110 so 3 movies will give Austin $330 meaning we only need $450 remaining to make the given amount so 15 commercials will make $450. So in total the 3 movie ($330) plus the 15 commercials ($450) will make the given amount ($780) meaning his songs where played in 3 movies and 15 commercials.
