Answer:
Step-by-step explanation:
Let p be the number of identical packages.
We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.
The total mass of Renna and her load of identical packages is 620 kg.
We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.
We can represent this information in an inequality as:
Therefore, the inequality can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
40/100= 56/x
40x=100(56)
40x=5600
Divide both sides by 40 to get x alone.
X=140
