Extracted text: Suppose that for a company manufacturing calculators, the cost, revenue, and profit equations are given by C=70,000 + 40x, R=300x- P=R-C 20 where the production output in 1 week is x calculators. If production is increasing at a rate of 600 calculators per week when production output is 4,000 calculators. Find the rate of increase (decrease) in cost. revenue. and profit. ... A) Costs are at the rate of S per week at this production level. (Simplify your answer.)
