Matt paid $55 at a restaurant. That amount included a 10% tip. What was the check amount before the tip?

As long as there was no tax, the check amount *before* the tip should be just $55. With the tip, it would be $60.50.

It would be 55-5.50 which is $49.50

If the discriminant, b² - 4ac is<u> positive</u>

<h3>How to complete the statement?</h3>

From the question, we have the following equation of discriminant

The discriminant (d) is calculated as

d = b² - 4ac

The solutions of a quadratic equation are dependent on the following conditions

This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive

Hence, the complete statement is (b) positive
