Ataxi company charges passengers $1.75 for a ride, no matter how long the ride is, and an additional $0.40 for each mile traveled. the rule mc014-1.jpg describes the relationship between the number of miles m and the total cost of the ride c. what is the charge for a 2.7-mile ride?

The cost of a ride depends totally on the number of miles traveled, plus a fixed charge of $1.75.

We can use the following notation to describe the rule:

C(m)=1.75 + 0.40 m   (dollars)

for example the cost of traveling 8 miles, is calculated by C(8):

C(8)=1.75+0.40*8=1.75+3.2 = 4.95  dollars.

the charge for a 2.7 mile ride is:

C(2.7)=1.75+0.40*2.7=1.75+1.08=2.83   dollars

$ 2.83
