What is the minimum whole number of packages Renna needs to remove from the elevator to meet the mass requirement?
Answer:
Part A. 37.4p ≥ 170
Part B. p ≥ 5 (rounding to the next whole)
Renna needs to remove at least 5 packages from the elevator to meet the mass requirement.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mass limit for the elevator = 450 kg
Renna and her load of packages mass = 620 kg
Each package mass = 37.4 kg
2. Write an inequality to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
Number of packages * Each package mass ≥ Renna and her load of packages mass - Mass limit for the elevator
Replacing with the values and variables we know:
p * 37.4 ≥ 620 - 450
37.4p ≥ 170
3. What is the minimum whole number of packages Renna needs to remove from the elevator to meet the mass requirement?
Solving for p in the equation above, we have:
37.4p ≥ 170
p ≥ 170/37.4
p ≥ 4.55
p ≥ 5 (rounding to the next whole)
5/t = t/45
