B. $3.75 per mile
The rate of change of the cost in dollars with respect to the number of miles is represented by the coefficient of x in the equation, which is 1.5. This means that for each additional mile traveled, the cost increases by $1.50.
The function y=3.75+1.5(x-1) can be used to determine the 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?
