Question

Emath has a stockpile of 1850 algebra textbooks. They are being purchased at a steady rate of 120 books per week. Write a linear function that models the number of books, b, left after w-weeks of sales

Answer 1

Answer: b = 1850 - 120w

Step-by-step explanation:

Let w represent the number of weeks for which the books are purchased.

They are being purchased at a steady rate of 120 books per week. This means that the number of books purchased after w weeks would be 120w.

The total number of algebra textbooks that she had initially is 1850

If b represents the number of books left after w-weeks of sales, then the linear function that models the number of books left after w weeks would be

b = 1850 - 120w
