Answer 1

To find out what value the contractor used for the weight of a person, we can set up an equation based on the total weight the porch needs to hold.

Given:

• Number of people = 20
• Weight of furniture = 250 lb
• Total weight the porch needs to hold = 3750 lb

First, let's subtract the weight of the furniture from the total weight:

3750 lb (total weight) - 250 lb (furniture) = 3500 lb (weight for people)

Next, we can find the weight of one person by dividing the total weight meant for people by the number of people:

3500 lb / 20 people = 175 lb per person

Therefore, the contractor used a value of 175 lb for the weight of a person.
