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.

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.

The correct answer would be shape of function b = 2× slope of function a.
