Solve the system of equations using inverse matrices.
Give your answer as an ordered triple.

A class reunion committee is planning for 400 guests for its 10-year-reunion. The guests can choose one of the three options for dessert: Cheesecake, which is $4 per serving, chocolate mousse, which is $2.50 per serving, and blueberry pie, which is $3 per serving. The chef preparing the desserts must spend 5 minutes on a pie, 8 minutes on mousse, and 12 minutes on cheesecake. The total cost of desserts was $1170, and the chef spent exactly 45 hours preparing them.
