Question

As Jackson built a square fence around his garden, he wondered how much he would have to pay if he increased the length of each side of the fence by the same number of meters. Each meter of fence costs 3 dollars. Which of the following functions best describes the additional amount of money Jackson will have to spend, in dollars, if he increases each side of the fence by m meters?

Answer 1

A good function for this situation would be

c = 4(3m)


C is the cost of it all, m is the number of meters. The 3 is how many dollars it costs for each individual meter, and the 4 is how the length would need to be applied to all four sides of the fence. Hope this helped!
