Mr. Greer is building a safety fence around the perimeter of his swimming pool.
• The perimeter of the swimming pool is 126 ft.
• Each section of the safety fence is 7 ft long and costs $16.
Which equation can Mr. Greer use to find c, the total cost of the safety fence he needs for the swimming pool?
126 divided by (16 divided by 7) = c
(16 X 7) X 126 = c
126 divided by (16 X 7) = c
(126 divided by 7) X 16 = c

Answer: (126 divided by 7) x 16 = c
Step-by-step explanation:
Perimeter = 126
Length of one section = 7
Cost of one section = $16
Number of section required = Perimeter/Length of one section
= 126/7
= 18
Cost of total number of sections = $18 x 16
= $288
Therefore, total cost of fencing = $288
Thus, the formula required is (126 divided by 7) x 16 = c
