Final answer:
Charles made a profit of £174 by selling 540 pens out of the 900 he purchased. He bought the pens for £258 and sold them for £432.
Step-by-step explanation:
The question involves calculating the profit Charles made from buying and selling pens. First, we need to calculate the total cost of the pens he purchased, then the revenue from the pens he sold, and finally, the profit by subtracting the cost from the revenue.
The question involves calculating the profit Charles made from buying and selling pens. First, we need to calculate the total cost of the pens he purchased, then the revenue from the pens he sold, and finally, the profit by subtracting the cost from the revenue.
Charles buys 60 packs of pens at £4.30 per pack. The total cost is:
60 packs × £4.30 per pack = £258
Each pack contains 15 pens, totaling:
60 packs × 15 pens per pack = 900 pens
Charles sells 3/5 of the pens at 80p each:
(3/5) × 900 pens = 540 pens sold
540 pens × £0.80 per pen = £432
The profit is the difference between the total revenue and the total cost:
£432 (revenue) - £258 (cost) = £174
Therefore, Charles made a profit of £174.
