The function y=3.75 + 1.5(x-1) can be used to determine cost in dollars for a taxi ride of x miles. what is the rate of change of the cost in dollars with respect to the number of miles?

1.5 dollars/miles

Step-by-step explanation:

Given function can be used to determine cost in dollars for a taxi ride of x miles.

Now we need to find about what is the rate of change of the cost in dollars with respect to the number of miles.

First we need to rewrite in y=mx+b form

comparing with y=mx+b, we get m=1.5

Hence rate of change of the cost in dollars with respect to the number of miles is 1.5.

they charge the same amount at 20 minutes.
