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? (1 point)
O 9.99 - 6.67p = 30, so p = 2
O 9.99 + 6.67p = 30, so p = 3
9.99p + 6.67p = 30, so p = 4
( 9.99p - 6.67p = 30, so p = 5

9.99 + 6.67p ≤ 30
Whats the full answer?
The maximum number of posters, p, that Lucia can buy is found by the inequality:
9.99 + 6.67p ≤ 30
To solve for p, we can subtract 9.99 from both sides:
6.67p ≤ 20.01
Next, we divide both sides by 6.67 to isolate p:
p ≤ 3
Therefore, Lucia can buy a maximum of 3 posters.
9.99 + 6.67p ≤ 30
To solve for p, we can subtract 9.99 from both sides:
6.67p ≤ 20.01
Next, we divide both sides by 6.67 to isolate p:
p ≤ 3
Therefore, Lucia can buy a maximum of 3 posters.
1. What is the first step in solving c + 2 = 10 *
• Add 2 to both sides
O Subtract 2 from both sides
• Multiply both sides by 2
Divide both sides by 2
• Add 2 to both sides
O Subtract 2 from both sides
• Multiply both sides by 2
Divide both sides by 2
The first step in solving c + 2 = 10 is to subtract 2 from both sides.
