QUESTION FIVE ") The number of shoppers queuing at any given time in a certain supermarket in downtown Nairohi can be apprecimatch represented by the equation! x - 14a + Six over the range 0 5 8 5 8.5, where y is the mummber queuing and a is the time in hours after the smire opens at 90lam. (So that, for example 10 30am, is =1.5, and 5.30p.m. - when the store chics is & = H.5). Required The management wants in know when they should deplay more cashiers and the number queuing at that time. ") Determine the number of man-hours spent per day by shoppers queuing bj An electronics firm carries out a small scale test launch of a new low-priced pocket calculator, It estimates from this best that If it went into full-scale production it would sell between 1000 and 2,500 calculators per month, and that its monthly revenue in thousands of shillings over this range of sales could be represented by the copiation Where! a is de monthly output in demands of calculuson de is assumed that it sells its entire output) From experience of calculator production, the firm estimates in marginal cost in thisands of shillings could be represented by the equation: and that its fixed costs will be Sh 500 per month. Required Determine the average cost and revenue equations for this firm, i] Determine the profit-maximizing output, the price that should be charged to maximize profit, and how much each calculator will then cost to make, ( 1 June 3101)
