(03.05 MC)

Rodney needs $90 to buy a fish tank. He has saved $35 and plans to work as a babysitter to earn $5 per hour. Which inequality shows the minimum number of hours, n, that Rodney should work as a babysitter to earn enough to buy the fish tank?

35 + 5n ≥ 90, so n ≥ 11
35 + 5n ≤ 90, so n ≤ 11

Cindy works in a cake shop and earns $42 per day. She earns an extra $4 for each cake she sells. If Cindy wants to earn at least $50 per day, which inequality shows the minimum number of cakes, n, that she should sell?

42 + 4n ≤ 50, so n ≤ 2
42 + 4n ≥ 50, so n ≥ 4
42 + 4n ≥ 50, so n ≥ 2
42 + 4n ≤ 50, so n ≤ 4
Question 12(Multiple Choice Worth 1 points)
(03.05 MC)

Lucia wants to buy some posters over the Internet. Each poster costs $6.67 and has a shipping cost of $9.99 per order. If Lucia wants to spend no more than $30 for her posters, which inequality shows the maximum number of posters, p, that she can buy?

9.99 − 6.67p ≤ 30, so p ≤ 2
9.99 + 6.67p ≤ 30, so p ≤ 3
9.99p + 6.67p ≤ 30, so p ≤ 4
9.99p − 6.67p ≤ 30, so p ≤ 5
