<strong>Journal</strong> 1. Explain the process that is used to fit a line to data.<br />
Multi-Step<br />
Problem<br />
2. A car wash charges a flat rate for the first 8 minutes of washing time <strong>and</strong> also<br />
charges a certain amount for each additional minute of washing time. Gina took<br />
12 minutes to wash her car <strong>and</strong> it cost her a total of $5.00. Kris took 17 minutes<br />
to wash his truck at a total cost of $6.25.<br />
a. Write an equation that models the total cost of a car wash as a function of<br />
the number of minutes spent washing a vehicle.<br />
b. How much is the flat rate for the first 8 minutes?<br />
c. How much is charged for each additional minute of washing time?<br />
d. It took Jermaine 15 minutes to wash his car. How much did he spend?<br />
e. Darci has $10 to spend at the car wash. What is the maximum number of<br />
minutes she can take to wash her vehicle?<br />
f. What is the slope of a line parallel to the line in part (a)?<br />
g. What is the slope of a line perpendicular to the line in part (a)?<br />
