You have decided that I want a solution for this problem: "A company is selling their new product, which consists of $12 million worth of computer mice and costs £5 per unit. The shop has 30% off-price on the first 5 units and an extra 15% discount on the next 74 units sold. What percentage of profit will be made by selling all these mouses at this special offer? Answer: To solve a similar problem, you can use the following equation: Profit = (Sale Price * Quantity) - Total Cost The sale price is £5 and there are 30% discount on the first 5 units and an extra 1 credits off on the next 74 units. So the sale price of each unit will be: Multiply(12,000) - Sale Price * Quantity * (1 - Discount)/100 Sale Price = £5 * (1 + 30/100%)
