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? (5 points) a 9.96p − 10.01p ≤ 50, so p ≤ 1 b 9.96p + 10.01p ≤ 50, so p ≤ 2 c 9.96 − 10.01p ≤ 50, so p ≤ 3 d 9.96 + 10.01p ≤ 50, so p ≤ 4

Answer:
9.96 + 10.01s ≤ 50, so s ≤ 4
Step-by-step explanation:
let
s ... number of books ( where s is any real number)
$10.01 * s + $9.96 < = $50
10.01 * s + 9.96 < = 50
10.01 * s < = 50 - 9.96
10.01 * s < = 40.04
s < = 40.04 / 10.01
s < = 4 books
The correct result would be 9.96 + 10.01s ≤ 50, so s≤ 4.
hope you find it helpful!!!!!!!!
