Answer:
Gym A is growing faster
Gym A 30 people per week
Gym B 15 people per week
Step-by-step explanation:
We can find the rate of change for Gym A
(2,20) and (4,80)
m = (y2-y1)/(x2-x1)
= (80-20)/(4-2)
=60/2
= 30 people per week
We can find the rate of change for Gym B
(2,70) and (4,100)
m = (y2-y1)/(x2-x1)
= (100-70)/(4-20)
= 30/2
= 15 people per week
