Question

If a barrel averages 50 pounds and a crate 120 ​pounds, write an inequality that describes when x barrels and y crates will cause the elevator to be overloaded.

Answer 1

We are given: Barrel quantity averages = 50 pounds.

Crate quantity = 120 pounds.

Number of  barrels is taken by variable x and

Number of crates is taken by variable y.

The elevator load should be greater than of total load.

Therefore,

50 * number of  barrels + 120 * number of crates > Total load.

50*x +120*y > Total load.

50x +120y > total load.
