You and your family will be taking a long vacation to a tropical island. your vacation will last 1 to 4 weeks, your parents haven't decided yet, how long they will stay. the island is so small that the resident dont use cars, but large enough that they do use other forms of transportation. there are two rental companies on the island. both have weekly rates.
scooters galore charges $50 up front and $15 per week
speedy's charges $20 up front, and $25 per week

show your family a graph comparing the cost for each company then make an equation to find the best deal for your family
