If production is increasing at a rate of 500 calculators per week when production output is 6,000 calculators. Find the rate of increase (decrease) in cost, revenue, and prot. P=R-C / A) Costs are at the rate of $|:| per week at this production level. (Simplify your answer.) B) Revenue is E at the rate of $D per week at this production level. (Simplify your answer.) C) Prots are at the rate of $D per week at this production level. (Simplify your - increasing k decreasing C) Time Remaining: 01:52:58 m
