chad wants to buy some books over the internet. each book costs $10.01 and has a shipping cost of $9.96 per order. if chad wants to spend no more than $50 for his books, which inequality shows the maximum number of books, p, that he can buy? 9.96p − 10.01p ≤ 50, so p ≤ 1 9.96p 10.01p ≤ 50, so p ≤ 2 9.96 − 10.01p ≤ 50, so p ≤ 3 9.96 10.01p ≤ 50, so p ≤ 4

If you would like to find the inequality that shows the maximum number of books that he can buy, you can do this using the following steps: p ... number of books $10.01 * p + $9.96 <= $50 10.01 * p + 9.96 <= 50 10.01 * p <= 50 - 9.96 10.01 * p <= 40.04 p <= 40.04 / 10.01 p <= 4 books The correct result would be 9.96 + 10.01p ≤ 50, so p ≤ 4.
