A bus company took a tour bus on the ferry when there were
30 people aboard. The ferry charged the bus company [tex]$180.
The following week, the bus had 50 people on board and the
ferry charged them $[/tex]220. How much is the "base rate" for the
empty bus? HINT: Find the equation of the line and x =0. SHOW
YOUR WORK.
1) Find the slope.
2) Use the point slope method to get the equation of the line.
Write the equation in Slope Intercept form.
3) Substitute 0 for x to get the answer.
