Question

5. Blade-Z manufactures roller blades. The production facility has fixed costs of $400 a day and total production costs of $4,400 per day at an output of 100 pair of skates per day. Which of the following equations represents the daily production cost for Blade-Z based on the number of skates manufactured?

(Let C(x) represent the daily production cost and x represent the number of pairs of skates manufactured.)
C(x) = 44x
C(x) = 40x - 400
C(x) = 44x + 400
C(x) = 40x + 400

Answer 1

100 pairs of skates costs 4400$ to produce so
one pair costs 44

there is a cost which is independent of how many pairs produced which is 400$
so
C(x) = 400 + 44x

Answer 2
