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 14 ounce cans and there are a combined total of 870 cans and bottles then 870 - x is the number of 70 ounce bottles  

 

The combined total weight of the cans and bottles is 

 

14*x + 70*(870 - x) 

14*x + 60900 - 70*x

-56*X + 60900
