Problem Page Lisa has a job transporting soft drinks by truc

Problem Page Lisa has a job transporting soft drinks by truck. Her truck is filled with cans that weigh 14 ounces each and bottles that weigh 70 ounces each. There is a combined total of 850 cans and bottles in her truck. Let x be the number of 14 -ounce cans in her truck. Write an expression for the combined total weight (in ounces) of the cans and bottles in her truck.

Solution

Let\'s assume  x be the number of 14 -ounce cans in her truck

and we are given cans that weigh 14 ounces each

weight of \'x\' cans = 14*x

we are given that

There is a combined total of 850 cans and bottles in her truck

so, total number of bottles=850-x

and we are given

bottles that weigh 70 ounces each

weight of (850-x) bottles= 70*(850-x)

now, we can find total weight

total weight = weight of \'x\' cans + weight of (850-x) bottles

total weight = 14x+70(850-x)

total weight = 59500-56x..........Answer
