Question

15. You take a trip to downtown Boston to walk the Freedom Trail with your family. After you walkthrough the Bunker Hill Memorial, your family decided to take a taxi to a restaurant for dinner. After 1mile, the meter on the taxi says $475. It will cost $6.50 to go 2 miles. The cost varies linearly with thedistance that you have traveled (In other words, there is a constant rate of change). What is the rate of change (slope)? Interpret it in context.

Answer 1

The slope is the rate of change, which means the cost per mile

Since the cost to go 2 miles is $6.50

Then to find the slope divide 6.50 by 2

`\begin{gathered} m=(6.50)/(2) \\ m=3.25 \end{gathered}`

The slope is 3.25

That means the cost per mile is $3.25
