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?

Respuesta :

Answer: 404

Step-by-step explanation:

First we got to subtract 471 out of 67

then we get 404 books

So, there were 404 more books sold than history books

Let ā€œbā€ represent the number of biology textbooks and ā€œhā€ 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.
