A retailer planned to buy some computers form a wholesaler for a total of shilling 1,800,000. Before the retailer could buy the computers the price per unit was reduced by shilling 4,000. This reduction in price enabled the retailer to buy five more computers using the same amount of money as originally planned.
(a) Determine the number of computers the retailer bought;
(b) Two of the computers purchased got damaged while in store, the rest were sold and the retailer made a 1 5% profit. Calculate the profit made by the retailer on each computer sold.
If the price was p, then
1800000/(p-4000) = 1800000/p +5
p = 40000
so, at $4000 each he could buy 45
at 3600 each, he could buy 50
he sold 48 computers for 1800000 * 1.15
