Question

A textbook store sold a combined 471 total of biology and history textbooks in a week. The number of biology textbooks sold was 67 more than the number of history textbooks sold. How many textbooks of each type were sold?

Answer 1

N/A

Explanation:

Answer 2

Let “b” represent the number of biology textbooks and “h” represent history textbooks.

b + h = 471

(h + 67) + h = 471

2h + 67 = 471

2h + 67 - 67 = 471 - 67

2h = 404

h = 202

Therefore, 202 history books were sold. We can correlate this with the total books to find that:

471 - 202 = 269

This means 269 biology books were sold.

Answer Recap: 202 history books were sold, and 269 biology books were sold.
