Question

Renaldo has a job transporting soft drinks by truck. HIs truck is filled with cans that weigh 32 ounces each and bottles that weigh 28 ounces each. There is a combined total of 100 cans and bottles in his truck. Let be the number of cans in his truck. Write an expression for the combined total weight (in ounces) of the cans and bottles in his truck

Answer 1

32c + 28b

c + b = 100

If c = 100 - b

32(100 - b) + 28b

If b = 100 - c

32c + 28(100 - c)

A more definite value is not possible.
