Amy helped her out aunt pick tomatoes from her garden. It was hard work and it made her back hurt, but it was worth it. Those juicy fresh tomato sandwiches would be delicious! They picked tomatoes from 7:32 a.m. until 12:15 p.m. For how long did Amy and her aunt pick tomatoes?

(60-32) + 4*60 + 15 = ___ minutes
