Question

A floor has six sections. The total weight supported by the floor at present is 120 pounds.

If the maximum weight that can be supported by the floor is 900 pounds, what is the maximum additional weight that each section of the floor can support. Give the correct answer and the correct equation required for solution.

Answer 1

Answer:

130 pounds

Step-by-step explanation:

The floor has six sections and supports a total weight of 120 pounds.

Thus,

the amount of weight supported by each section of the floor  = $\frac{120}{6}$

                                = 20 pounds

But, the floor can support maximum weight of 900 pounds.

Thus,

maximum weight that can be supported by each section of the floor = $\frac{900}{6}$

                                 = 150 pounds

Let the maximum additional wight be represented by x. The maximum additional weight that each section of the floor can support can be determined by;

                       150 = 20 + x

                         x = 150 - 20

                         x = 130

The maximum additional weight that can be supported by each section of the floor is 130 pounds.
