work out the total amount Adam earned last week

Adam earned a total of £265.10 last week.

Step-by-step explanation:

Step 1; Adam earns a basic pay of £200 each week. He earns 10% of the magazine price for each sold and 15% of the book price for each sold. Each magazine costs £8 and each book costs £15. He sells 42 magazines and 14 books.

Money earned for selling a magazine = 10% * £8 = 0.10 * £8 = £0.80,

Money earned for selling a book = 15% * £15 = 0.15 * £15 = £2.25,

Money earned for selling 42 magazines = 42 * £0.80 = £33.60,

Money earned for selling 14 books = 14 * £2.25 = £31.50,

Money earned for selling 42 magazines and 14 books = £33.60 + £31.50 = £65.10.

Step 2; Now we have to calculate his last week's salary which is his weekly pay and his earnings from selling magazines and books. We found that he earned £31.50 from selling books and magazines. His weekly salary is £200.

Last week's salary = £200 + £65.10 = £265.10.
