number of small trucks --- x
number of vans ----- 2x
number of large trucks = 280 - 3x
30,000x + 25,000(2x) + 40,000(280-3x) = 8,000,000
divide by 5000
6x + 10x + 8(280-x) = 1600
carry on
The U-Drive Rent-A-Truck company plans to spend $8 million on 280 vehicles. Each commercial van will cost $25,000, each small truck $30,000, and each large truck $40,000. Past experience shows that they need twice as many vans as small trucks. How many of each type of vehicle can they buy?'
