Suppose that Andy sells basketballs in the perfectly competitive basketball market. His output per day and his costs are as follows: Output Per Day Total Cost Variable Cost Average Total Cost Average Variable Cost Marginal Cost 0 $10.00 $0 -- -- -- 1 15.00 5 $15.00 $5.00 $5.00 2 17.50 7.50 8.75 3.75 2.50 3 22.50 12.50 7.50 4.17 5.00 4 30.00 20.00 7.50 5.00 7.50 5 40.00 30.00 8.00 6.00 10.00 6 52.50 42.50 8.75 7.08 12.50 7 67.50 57.50 9.64 8.21 15.00 8 85.00 75.00 10.63 9.38 17.50 9 105.00 95.00 11.67 10.56 20.00 Suppose the equilibrium price of basketballs is $2.50. In the short run, how many basketballs will Andy produce? nothing (enter a whole number). How much profit (or loss) will he make? $nothing per day (round your answer to the nearest penny, and express a loss as a negative number).

Quick calculate the roi dollar amount and percentage for these example investments. a. you invest $50 in a government bond that says you can redeem it a year later for $55. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage. b. you invest $200 in stocks and sell them one year later for $230. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage.
