Question

Define a function f that determines the amount that Nicole pays (in dollars) for gas to drive m miles, given that Nicole's car gets 25 miles per gallon and gas costs $3.20 per gallon.

Answer 1

Answer:

  f(m) = 0.128m

Step-by-step explanation:

cost per mile = (cost per gallon)/(miles per gallon) = $3.20/25 = $0.128

Then the desired function is ...

  f(m) = 0.128m
