Ataxi charges a base fee plus $0.75/km.
a 10-km trip costs $8.70.
a) what is the rate of change in this situation?
b) write an equation for the cost of hiring a taxi in terms of length of the trip.
c) what does initial value represent in this situation.

a)  $0.75/Km

b)

c) The fixed base charge

Step-by-step explanation:

We know the taxi charges $0.75 per km and we are told a 10-Km trip costs $8.70. We can clearly see there is a base charge and a variable charge

a) The rate of change tells us the variation of the charges with the distance of the trip. In this case, the rate of change is $0.75/Km

b) If x is the length of the trip in Km, the equation of the total fare F(x) is

We know a 10-Km trip costs $8.70. Replacing those values would give us the value of A

8.70=A+0.75(10)

8.70=A+7.5

Using the value of A we have

c) The initial value represents the charge a customer has to pay even if they don't travel any distance, i.e. the fixed base charge
