Giselle is going to rent a scooter for at least one hour. The fee is $45 plus $5 for each hour it is rented. Write a function rule to describe the total cost of renting a scooter. Find a reasonable domain and range for the function if Giselle has $65.

  • algebra -

    c = 45 + 5 t

    she could rent it for zero hours and pay 45. That would not be smart so start at one hour. t = 1 and c = 50
    If she rents it for 4 hours, her wallet is empty. so t = 4 and c = 65 is the max of domain and range.
    domain 1 to 4 hours
    range 50 to 65 dollars
