Question

Abdul has a job transporting soft drinks by truck. his truck is filled with cans that weigh 14 ounces each and bottles that weigh 70 ounces each. there is a combined total of 870 cans and bottles in his truck. let x be the number of 14 -ounce cans in his truck. write an expression for the combined total weight (in ounces) of the cans and bottles in his truck.

Answer 1

If x is the number of cans, 870-x is the number of bottles

The weight of 1 can is 14oz, the weight of x cans is 14x
The weight of 1 bottle is 70oz, the weight of 870-x bottles is 70(870-x)

The weight in total is 14x+70(870-x)
