Question

Brian 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 790 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

Step-by-step explanation:

x = number of cans.

790 total cans and bottles.

790 - x = number of bottles.

y = weight of the cans and bottles in ounces.

y = 14x + 70×(790 - x) = 14x + 55300 - 70x = 55300 - 56x
