Question

a freight elevator has a weight limit of 2 tons. each crate that is loaded weighs 80 pounds. what is the greatest number of crates that can be loaded onto the elevator? (1 ton = 2,000 pounds) options: 160, 25, 500, 50

Explanation:

Step1: Convert tons to pounds

The weight limit is 2 tons. Since 1 ton = 2000 pounds, then 2 tons = \(2\times2000 = 4000\) pounds.

Step2: Calculate number of crates

Each crate weighs 80 pounds. Let \(n\) be the number of crates. We need to find the largest \(n\) such that \(80n\leq4000\). Solving for \(n\), we get \(n=\frac{4000}{80}=50\).

Answer:

50
