Two sand hauling trucks one that holds 12 tons and one that holds 15 tons make a total of 20 trips to haul 273 tons of sand. How many trips does each truck make?
(11) 15 tons loads, (9) 12 ton loads.
Insufficient data. A 2 variable equation requires 2 separate equations to solve. Also, the assumption that the trucks were full is implied but unstated.
LOL.
However, assuming full trucks, each truck made 7 trips.
Or the 15 ton truck made 15 trips, and each 12 ton truck made 2.
