Answer:
c) C(x) = 32x+ 130000 ; R(x) = 66x; P(x) = 34x− 130000
Step-by-step explanation:
If x is the number of units, and if each unit costs $32 to produce, the cost function must include the term 32x. If additional fixed costs are 130000, the cost function must show that added to the per-unit costs:
C(x) = 32x +130000 . . . . . matches choices (a) and (c) only
These answer choices agree that the revenue function is ...
R(x) = 66x
Of course, the profit function is their difference:
P(x) = R(x) -C(x) = 66x -(32x +130000)
Since the minus sign gets distributed to both terms inside parentheses, the profit function simplifies to ...
P(x) = 34x -130000 . . . . . matches choice (c)
