Answer and Step-by-step explanation:
To find the percentage profit that Rubab makes on the books, we need to calculate her total cost and total revenue. Let's break it down step by step:
1. Total cost:
Rubab buys 130 books for $2,013. To find the cost of each book, we divide the total cost by the number of books:
Total cost / Number of books = Cost per book
$2,013 / 130 = $15.48 (rounded to two decimal places)
2. Total revenue:
Rubab sells each book for $5.40, so to find her total revenue, we multiply the selling price by the number of books:
Selling price per book x Number of books = Total revenue
$5.40 x 130 = $702
3. Profit:
To calculate the profit, we subtract the total cost from the total revenue:
Total revenue - Total cost = Profit
$702 - $2,013 = -$1,311
4. Percentage profit:
To find the percentage profit, we divide the profit by the total cost and multiply by 100:
(Profit / Total cost) x 100 = Percentage profit
(-$1,311 / $2,013) x 100 = -65.1%
Therefore, Rubab makes a percentage profit of -65.1% on the books. Note that the negative sign indicates a loss rather than a profit.
