Answer:
A. C(x) = 30.000 + 2500x
B. R(x) = 3125x
C. 48 items break even point
Explanation:
A. The cost function C(x) is fixed cost plus variable cost.
In this case overhead works as fixed cost, we can write:
C(x) = 30.000 + 2500x
B. Revenue R(x) would be the price multiplied by quantity of items (x).
R(x) = 3125x
C. Break even point
To get the break even point we set R(x) = C(x) and find the value of x.
R(x) = C(x)
3125x = 30.000 + 2500x
3125x-2500x=30.000
625x=30.000
x=30.000/625
x=48
It means when you sell 48 items the costs will even revenue. So if you sell more than 48, then it's going to be profitable. If you sell less than 48, you will be losing money.
