Question 1087567: A car service charges $12 to pick up a passenger, and 40 cents per mile for any trip.
Write a linear function which models the total charge for a fare F(in$) as a function of total distance of the trip d(in miles).
F(d)=
How far(in miles) can the passenger travel with $48?
d=

+F%28d%29+=+12+%2B+.4d+
------------------------
+F%28d%29+=+48+
+48+=+12+%2B+.4d+
+.4d+=+36+
+d+=+90+
The passenger can travel 90 miles on $48
