The cost of a ride depends totally on the number of miles traveled, plus a fixed charge of $1.75.
We can use the following notation to describe the rule:
C(m)=1.75 + 0.40 m (dollars)
for example the cost of traveling 8 miles, is calculated by C(8):
C(8)=1.75+0.40*8=1.75+3.2 = 4.95 dollars.
the charge for a 2.7 mile ride is:
C(2.7)=1.75+0.40*2.7=1.75+1.08=2.83 dollars
Answer:$ 2.83
