Question

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

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.
