Explanation
Calculate the total cost of the books First, we need to determine the total cost of the books. The student bought 13 books at N450.25 each. To find the total cost, we multiply the number of books by the cost per book.
Total cost of books 13 × 450.25 = 5853.25
Calculate the total cost of exercise books Next, we need to determine the total cost of the exercise books. The student bought 9 exercise books at N80.50 each. To find the total cost, we multiply the number of exercise books by the cost per exercise book.
Total cost of exercise books 9 × 80.50 = 724.50
Calculate the total amount spent Finally, we need to find the total amount the student spent. To do this, we add the total cost of the books and the total cost of the exercise books.
Total amount spent 5853.25 + 724.50 = 6577.75
Final Answer Therefore, the student spent N6577.75 altogether.
