Question

The 450 juniors at East HS drink a total of 1500 cartons of milk per 5-day week. If the average senior drinks milk at the same rate as the average junior, what is the average number of total cartons of milk the 600 seniors drink each school day?

Accepted Answer

If 450 juniors drink 1500 cartons in 5 days, they drink 300 cartons per day. 600 seniors drink 600/450=4/3 as much milk as 450 juniors, so they drink 300 (4/3) = 400 cartons of milk a day.
