If 4 quarts of paint are needed for a 75-foot fence, how many quarts are needed for an
825-foot fence?

44 quarts of paint

Step-by-step explanation:

Given,

75-foot fence needs = 4 quarts.

We have to use the unitary method to determine how many quarts will be needed for the fencing system. Hence,

75-foot fence needs         = 4 quarts of paint

1-feet fence needs            = (4/75) quarts of paint

825-foot fence needs      = (4 x 825)/75 quarts of paint

                                          = 3,300/75 quarts of paint

                                          = 44 quarts of paint

Therefore, we need 44 quarts of paint for 825-foot fence.
