- D.1.arrow_forwardAn electronics company makes communications devices for military contracts. The company just completed a large contract. The Army contract was for 6808 devices that were produced by 43 workers in three weeks. Each worker worked 40 hours per week. What was the prductivity for the ARMY contact in devices per labour hour? (State your answer rounded to two decimal places)arrow_forwardThe Potomac Range Corporation manufactures a line of microwave ovens costing $500 each. Its sales have averaged about 6,000 units per month during the past year. In August, Potomac's closest competitor, Spring City Stove Works, cut its price for a closely competitive model from $600 to $545. Potomac noticed that its sales volume declined to 4,500 units per month after Spring City announced its price cut. a) What is the arc cross elasticity of demand between Potomac's oven and the competitive Spring City model? b) If Potomac knows that the arc price elasticity of demand for its ovens is −2.0, what price would Potomac have to charge to sell the same number of units it did before the Spring City price cut?arrow_forward
- a bakery charges $ 1.50 for donuts , and $ 2.25 for its scones. one day the manager found out that 150 scones had been sold out , and the total recepits were $ 258. how many donuts and scones were sold?arrow_forwardInitial values are: PM $20000 PG = $1.00 I = $15000 A = $10000 QT 200 -.01PT +.005PM -10PG +.011 +.003A This function is: 1.(a). Use the above to calculate the arc price elasticity of demand between Pr = $20000 decreasing to PT = $10000. AQ P₁ + P₂ The arc elasticity formula is:Ep ΔΡ Q₁ +2₂ (b). Judging from the computation in (1a), do you expect the revenue resulting from the price decrease to $10000 to increase, remain the same, or decrease relative to the revenue at the price of $20000? (Hint: see the table on page 65 of Truett). Explain your choice. 2.(a) Calculate the point price elasticity of demand for Toyotas at PT= $20000 (which should make Q₁ = 270). Other variables and their values are given at the top, before question #1. The formula is: dQT PT Ep = ● арт LT (b). Does this elasticity indicate that Toyota demand is relatively responsive to changes in Toyota price? Explain why or why not. 3.(a). Calculate the point gasoline cross-price elasticity between (PG) and Toyota…arrow_forwardA lash adjuster keeps pressure constant on engine valves, thereby increasing fuel efficiency in automobile engines. The relationship between price (p) and monthly demand (D) for lash adjusters made by the Wicks Company is given by this equation D (1.900-py0 10 What is the demand (0) when total revenue is maximized? What important data are needed if maximum profit is desired? G The total revenue is maximized when demand is 9500 units per month (Round to the nearest whole number) Select all important data that are needed if maximum profit is desired. DA Variable cost per lash adjuster B. Fixed cost per month C. Variable cost per engine valve D. Variable cost per gallon of fuelarrow_forward
- Davis Stores sells clothing in 15 stores located around the southwestern United States. The managers at Davis are considering expanding by opening new stores and are interested in estimating costs in potential new locations. They believe that costs are driven in large part by store volume measured by revenue. The following data were collected from last year’s operations (revenues and costs in thousands of dollars). Store Revenues Costs 101 $4,120 $4,244 102 2,247 2,934 103 5,768 5,211 104 4,022 4,048 105 2,944 3,736 106 4,063 3,389 107 6,914 5,059 108 1,809 2,474 109 5,516 4,768 110…arrow_forwardYou are analysing the annual revenue from the top 5 coffee maker models manufactured in your company, and want to know the comparative revenue made from each model.
