Question

the equation for the line of best fit is y = 0.8x + 30. according to the equation, which of these statements is true? on a day when the theater sells 550 tickets, the snack stand would likely use about 470 ounces of butter. on a day when the theater sells 600 tickets, the snack stand would likely use about 480 ounces of butter.

Explanation:

Step1: Analyze the first statement

We are given the equation \( y = 0.8x+30 \), where \( x \) is the number of movie tickets sold and \( y \) is the ounces of butter used. For the first statement, \( x = 550 \). Substitute \( x = 550 \) into the equation:
\( y=0.8\times550 + 30 \)
\( y = 440+30=470 \)

Step2: Analyze the second statement

For the second statement, \( x = 600 \). Substitute \( x = 600 \) into the equation:
\( y=0.8\times600+30 \)
\( y=480 + 30=510
eq480 \)

Answer:

On a day when the theater sells 550 tickets, the snack stand would likely use about 470 ounces of butter.
