Three ice cream shops have provided quotes for catering Martina’s ice cream party. Each store charges a delivery fee in addition
to a price per person. Each store gives Martina its pricing plan in a different way, as shown below, where C is the total cost in dollars and n is the number of people who will attend the party.
Igloo Ice: C(n) = 1.75n + 75
Fred's Freeze: C(n) = 2n + 80
Tasty Treats: C(n) = 1.25n + 90
Which store has the lowest delivery charge: Igloo, Fred's, or Tasty?
