Answer:
65.5%
Explanation:
The total cost of making 1000 lapel pins is:
Cost = 1000 * £1.10
= £1100
Out of these, 35% of the lapel pins are given to charities. So, the number of lapel pins that will be sold is:
Number of lapel pins for sale = 1000 - 35% of 1000
= 1000 - 350
= 650
60% of these lapel pins are sold at £3.00 each. So, the revenue from selling these lapel pins is:
Revenue from selling 60% of the lapel pins = 60% of 650 * £3.00
= 390 * £3.00
= £1170
40% of the remaining lapel pins are sold at £5.00 for 2. This means that for every 2 lapel pins sold, the revenue is £5.00. So, the revenue from selling these lapel pins is:
Revenue from selling 40% of the lapel pins = 40% of 650 / 2 * £5.00
= 130 * £5.00
= £650
The total revenue from selling the lapel pins is:
Total revenue = Revenue from selling 60% of the lapel pins + Revenue from selling 40% of the lapel pins
= £1170 + £650
= £1820
The profit is the difference between the revenue and the cost of making the lapel pins. So, the profit is:
Profit = Total revenue - Cost
= £1820 - £1100
= £720
The percentage profit is the profit as a percentage of the cost, multiplied by 100. So, the percentage profit is:
Percentage profit = (Profit / Cost) * 100
= (£720 / £1100) * 100
= 65.45%
Therefore, the company should make a percentage profit of 65.5%.
