The answer to this is; B)
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. ;)
1 km = 1000m
so 4 km = 4(1000) = 4000 m
so Kali runs 4000 m per day
4000/400 = 10 laps per day
for 3 days = 3(10) = 30 laps for 3 days
