Question

Sheryl takes a summer job selling hats for a local soccer team. She realizes that there is a relationship between the number of games the team wins each season and the number of hats vendors like her tend to sell. She collects data from the past several seasons. The scatter plot shows her data and the line of best fit.
Using technology, she finds that the equation of the line of best fit is y = 3.75x + 13.75.

Based on the equation for the line of best fit, about how many hats can Sheryl predict she will sell if the team wins 9 games this season?

A.
48 hats
B.
42 hats
C.
9 hats
D.
10 hats

Answer 1

Answer:

47

Step-by-step explanation:

x is games won

y is hats sold

$y=3.75x+13.75\\y=3.75(9) + 13.75\\y=47.5$

Since you can't sell .5 of a hat- you need to round this answer.
