Question

Determine which gym's membership grows faster from Month 2 to Month 4 by calculating the average rates of change.

Answer 1

Gym A is growing faster

Gym A gained 13 members between months 2 and 4

Gym B gained 10 members between months 2 and 4

Explanation:

Gym A: (2,20) (4,46)

rate of change = (46-20)/(4-2) = 26/2 or 13

Gym B: (2,40) (4,60)

rate of change = (60-40)/(4-2) = 20/2 or 10
