Acompany manufacturing snowboards has fixed costs of $200 per day and total costs of $3,800 per day for a daily output of 20 boards.
1. assuming that the total cost per day, c(x), is linearly related to the total output per day, x, write an equation for the cost function.
2.the average cost per board for an output of x boards is given by c(x) = c(x) / x. find the average cost function.
3. sketch a graph of the average cost function, including any asymptotes, for 1 < _ x < _ 30.
4. what does the average cost per board tend to as production increases?

the correct answer is the second option

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
