Question

The table shows some values that satisfy the quadratic equation. Which of the following is a true statement?

Answer 1

Answer:

Option B is the true statement.

Step-by-step explanation:

The given quadratic equation is y = (-6x² + 100x - 180)

In this equation y represents the daily profit and x represents the selling price.

Now we will check every option given.

A. If the selling price per ball is $5 then profit will be

y = -6×25 + 100×5 - 180 = -150 + 500 - 180 = $170

Which never defines the number of balls sold, so option A. is not correct.

B. If the selling price is $8 then profit will be

y = -6×64 + 800 - 180 = -384 + 800 - 180 = $236

This option is correct.

C. This option is not valid because we can't use number of balls to find the profit.

D. This statement is also not correct as we can see if selling price of a ball is $5 then profit is $170 and when selling price is $12 then profit is $156.

Therefore this option is also not correct.

Option B is the answer.

Answer 2

Selection B is appropriate.

_____
It's about matching the meanings of x and y. Both are dollars. Neither is a count of soccer balls. The table shows that when price goes up beyond a certain point, profit goes down.
