The parent volunteers:
120 snow cones ... 5 hours
x snow cones = ? ... 1 hour
120 1 = 5 x
120 = 5 x /5
x = 120 / 5 = 24 snow cones
The student council:
100 snow cones ... 4 hours
y snow cones = ? ... 1 hour
100 1 = 4 y
100 = 4 y /4
y = 100 / 4 = 25 snow cones
Result: The student council made more snow cones per hour (25 > 24).
