Question

Renna pushes the elevator button, but the elevator does

not move. The mass limit for the elevator is 450
kilograms (kg), but Renna and her load of identical
packages mass a total of 620 kg. Each package has a
mass of 37.4 kg
Write an inequality to determine the number of
packages, p, Renna could remove from the elevator
to meet the mass requirement.

Answer 1

The inequality is: 620 - 37.4p ≤ 450

Renna needs to remove a minimum of 5 packages from the elevator to meet the mass requirement.

Answer 2

`620-37.4p\leq 450`

4 box removed from the elevator.

Explanation:

Given:

Number of package = p

The The mass limit for the elevator is 450 kilograms (kg)

Ronna and her load of identical packages mass a total of 620 kg.

Each package mass = 37.4 kg

Find the inequality to determine the number of

packages, p, Renna could remove from the elevator to meet the mass requirement.

So , the difference between the total mass and mass of package p is less than or equal to mass limit of an elevator

So, the inequality is.

____________________________

`620-37.4p\leq 450`

-----------------------------------------------------

Solve above inequality for number of package.

`620-450\leq 37.4p`

`37.4p\leq 170`

`p\leq (170)/(37.4)`

`p\leq 4.54`

Therefore, 4 box removed from the elevator.
