The boy bought 5 oranges for #24.00. Therefore, the cost price per orange is: c.p = \(\frac{24}{5}\) = #4.800 The boy sold 4 oranges for #30.00. Therefore, the selling price per orange is: s.p = \(\frac{30}{4}\) = # 7.50 Profit per orange is calculated as: Profit per orange = SP per orange − CP per orange = =7.50 − 4.80 = 2.70 If the boy sold 4 oranges, the total profit from selling 4 oranges is: Total Profit = 4 × 2.70 = #10.80
