Answer: For groups with over 3 people, Family Fun Land is the best option. It's cheapest for groups of 1 or 2 to go to Blue Jay Bay.
Explanation:
Family Fun Land | y = total $, x = # of people
y = 12x + 40
Blue Jay Bay
y = 22x + 12
2 People
y = 12(2) + 40
y = 64
y = 22(2) + 12
y = 56
3 People
y = 12(3) + 40
y = 76
y = 22(3) + 12
y = 78
