Mari must sell more than 36 cups of lemonade to make profit

<h3>How to draw the number line?</h3>

The complete question is added as an attachment

From the question, we have:

Start up cost = $18

Let the amount per cup of lemonade be $0.5, and the number of cups be x

So, the total amount in sales is:

Total = 0.5 * x

Evaluate

Total = 0.5x

When Mari’s lemonade stand makes a proﬁt, we have:

Total sales > Start up cost

This gives

0.5x > 18

Divide both sides by 0.5

x > 36

Hence, Mari must sell more than 36 cups of lemonade to make profit
