A computer manufacturer produces a certain electronic component at a cost of $80 per component. Shipping costs for delivering the components are $2 per unit. Further, the manufacturer has costs of $16,500 a month related to the electronic component regardless of how many it produces. If the manufacturer produces and sells 150 components a month, what is the lowest price it can sell them for such that the costs don't exceed the revenues?
A. $28
B. $82
C. $110
D. $138
E. $192
Kudos for a correct solution.
VERITAS PREP OFFICIAL SOLUTION:Solution: E. For the costs to equal the revenues, align all the costs on one side of the equation and then the revenues on the other: Cost = Revenue.
The costs consist of the $16,500 fixed cost plus $82 per unit, so the costs are 16500 + 82(150). The revenue is the sale price times the number of units, which we know is 150. So our equation is:
16500 + 82(150) = x(150)
Rather than multiply 82 by 150, you may want to finagle the algebra to make it quicker. If you get the 150s on the same side, you can factor them:
16500 = x(150) - 82(150) 16500 = 150(x - 82) 16500/150 = x - 82
Now you can do the division on the left:
16500/150 = 1650/15 = 110
And so 110 = x - 82. Add 82 to both sides and you have your answer: x = 192, answer choice E.
