Revenue and Profit Billy-Sean O’Hagan is John O’Hagan’s son and a freshman in college. He notices that the demand for the college newspaper was 2,000 copies each week when the paper was given away free of charge but dropped to 1,000 each week when the college started charging 10¢/copy.
a. Write down the associated linear demand function.
b. Use your demand function to express the revenue as a function of the unit price p. Hence, determine the price the college should charge for a maximum revenue. At that price, what is the revenue from sales of one edition of the newspaper?
c. It costs the college 4¢ to produce each copy of the paper plus an additional fixed cost of $200. Express the profit P as a function of the unit price p. Hence, determine the unit price the college should charge for a maximum monthly profit (or minimum loss). What is the resulting profit (or loss)?

The first earns 10% compounded annually, the second earns 10% compounded quarterly, and the third earns 10% compounded continuously. Find equations that model each investment growth and use a graphing utility to graph each model in the same viewing window over a 20-year period. Use the graph to determine which investment yields the highest return after 20 years. What are the differences in earnings among the three investment? STEP 1: The formula for compound interest is A = nt = P(1 + − − ) n², where n is the number of compoundings per year, t is the number of years, r is the interest rate, P is the principal, and A is the amount (balance) after t years. For continuous compounding, the formula reduces to A = Pert Find r and n for each model, and use these values to write A in terms of t for each case. Annual Model r=0.10 A = Y(t) = 1150 (1.10)* n = 1 Quarterly Model r = 0.10 n = 4 A = Q(t) = 1150(1.025) 4t Continuous Model r=0.10 A = C(t) =…arrow_forwardUse a graphing utility to find the point of intersection, if any, of the graphs of the functions.
