Question

The admission fee at an amusement park is $12, and each ride costs $3.50. The park also offers an all-day pass with unlimited rides for $33. For what numbers of rides is it cheaper to buy the all-day pass?

Answer 1

Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)
