Can you guys help me solve this problem

528

Step-by-step explanation:

First we have to find the price per case.

We can do this by dividing 408 by 17, because we know that 17 cases cost 408 and each case will cost the same.

408/17= 24

Now we can find the price of the five cases they want to add.

24 X 5 = 120

Now we just add that price back to original order price.

408 + 120 = 528

answer: 8.5x + 20 < 54

Less than 4 tubes.

Step-by-step explanation:

Assume that x represents the number of tubes of paint Catherine can buy.

Catherine has $54. She plans to spend more than $20 of the money for a painting canvas. The rest will go toward paints. This means that the amount she has to spent on paint is < 54 - 20

Each tube of paint costs $8.50. The cost of x tubes of paint would be 8.5x

Therefore, the inequality that best represents the scenario is

8.5x < 54 - 20

8.5x + 20 < 54

The number of tubes that she can buy is

8.5x < 34

x < 34/8.5

x < 4

Less than 4 tubes
