Question

The total amount of weight on an elevator cannot exceed 1,800 pounds. a delivery person is on the elevator delivering packages. together, the delivery person and the packages weigh 520 pounds. if the average weight of a person is 160 pounds, set up and solve an inequality to determine how many additional people, p, the elevator can hold.

Answer 1

p ≤ 8

Explanation:

Given the following :

Maximum weight elevator can hold ≤ 1800

Weight of delivery person and packages = 520 pounds

Average weight of a person = 160 pounds

Inequality to show how many additional people elevator can hold?

(weight of delivery person and packages + average weight of persons * number of persons) ≤ 1800

Let p = number of persons

(520 + 160p) ≤ 1800

160p ≤ 1800 - 520

160p ≤ 1280

p ≤ 1280 / 160

p ≤ 8
