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
