Question

The cost to produce x units of wire is C = 35x + 500, while the revenue is R = 60x.

Find all intervals where the product will at least break even.


Select the correct choice below and, if necessary, fill in the answer box to complete your choice.


A. The inequality in interval notation is


B. The product will never break even.

Answer 1

Answer:

n order for the product to at least break even, the revenue must be equal to or exceed the cost. To solve for this interval we set R>=C. So,  

45x>=20x+550. Once we solve this equation we get x>=22 so the interval where the product will at least break even

so the answer is B.
