Combined Mass of truck and wheat (t):
16.2
21.6

Bushels of Wheat (Bu):
300
500


a) write a linear equation to represent this situation. Use this equation to determine the combined mass of the truck and the wheat in tonnes when the truck is loaded with 600 bushels of wheat.

b. Use the equation to determine the mass of the farmer's truck in tonnes.
