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)


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

9,96+10,01p< or equal 50
10,01p< or equal 50-9,96
10,01p < or equal 40,04
p < or equal 40,04:10,01
p < or equal 4

Hello! $9.96 is the one time price for shipping, but you pay $10.01 per book. The words "no more than" means less than or equal to. You would set the inequality up like this: 9.96 + 10.01p <= 50. With that being the case, A and C are both eliminated, because you don't subtract. We can solve the inequality by subtracting 10.01 from both sides to get 9.96p <= 39.99 and divide by 9.96p to get p = 4.0150 and other numbers behind it or just simply 4 when rounded to the nearest whole number. p <= 4. The answer is D.
