Pedro wants to buy some shirts over the Internet. Each shirt costs $10.01 and has a shipping cost of $9.94 per order. If Pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy?
9.94 + 10.01p ≤ 70, so p ≤ 6
9.94 − 10.01p ≤ 70, so p ≤ 7
9.94p + 10.01p ≤ 70, so p ≤ 8
9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

Question

Pedro wants to buy some shirts over the Internet. Each shirt costs $10.01 and has a shipping cost of $9.94 per order. If Pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy?
 9.94 + 10.01p ≤ 70, so p ≤ 6
 9.94 − 10.01p ≤ 70, so p ≤ 7
 9.94p + 10.01p ≤ 70, so p ≤ 8
 9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

anonymous · Answer

9.94 + 10.01p <= 70 if you solve for p you'll find that p <= 6
