Question

the derp car rental company uses function f(x)=26 for any daily use of a car up to and including 250 miles. For driving more than 250 miles per day, it uses function g(x) = 26 + 0.1 (x-250) to determine the charges, where x is the number of miles driven. How much would the derp company charge for daily driving of 160 miles?

Answer 1

"x" is the numbers of miles right?
just substitue 160 instead of x.

Answer 2

26 + 0.1 (x-250)
26 + 0.1(160-250)
26 + 0.1(-90)
26 - 9
