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?

6.67p+9.99≤30

....

subtract 9.99 from both sides

6.67p≤20.01 divide both sides by 6.67

p≤3

So the maximum number of posters that she can buy is 3.

I think it is 9.99+6.67p<=(less than or equal to)30 so, p<=3
Hope that helps!
