can you help me solve the following question:
Suppose that the revenue from selling x thousand medical newsletters is given by R(x) =32x − 0.21×2 and that the total cost from producing x thousand medical newsletters is C(x) = 195 + 12x. Both R(x) and C(x) are in thousands of dollars.
(a) Determine the number of newsletters to be sold in order to break even. (If there are multiple break even quantities, list all of them.) Include units in your answer.
(b) How many units should be sold in order to maximize the proﬁt? And, what is the maximum proﬁt? Justify your answer using methods discussed in this course and include units in your answer.
