Answer:
Cost to travel 75 miles = 11.55 $
Explanation:
A scooter can travel between 22 and 28 miles on each gallon of gasoline.
Average distance a scooter can travel with each gallon of gasoline = (22+28)/2 = 25 miles.
One gallon of gasoline costs between $3.75 and 3.95 per gallon.
Average cost for one gallon of gasoline = (3.75+3.95)/2 = 3.85 $
We need to find cost for traveling 75 miles.
Gasoline required = Total miles/ Average distance a scooter can travel with each gallon of gasoline
= 75/25 = 3 gallons.
Cost to travel 75 miles = Gasoline required x Average cost for one gallon of gasoline
= 3 x 3.85
= 11.55 $
