Using proportions, it is found that the elevator will be safe, as the total weight of 2.2075 tons is less than the maximum load restriction of 2.5 tons.
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Each lb has 0,0005 tons. Hence the total weight in tons that we want to put in the elevator is:
T = (175 + 240 + 80 x 50) x 0.0005 = 2.2075 tons.
Hence, the elevator will be safe, as the total weight of 2.2075 tons is less than the maximum load restriction of 2.5 tons.
