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 “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.
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.
