Question

Renna pushes the elevator button, but the elevator does not move. The mass limit for the elevator is 450kg, but Renna and her load of identical packages mass a total of 620kg. Each package has a mass of37.4kg Write an inequality to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.What is the minimum whole number of packages Renna needs to remove from the elevator to meet the mass requirement?

Answer 1

To determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement, we can set up an inequality. The total mass of Renna and her load of packages should be less than or equal to the mass limit of the elevator.

The inequality is: 37.4p + Renna's mass ≤ 450

To find the minimum whole number of packages Renna needs to remove, we can solve this inequality for p.
