Two gyms open their memberships to the public. Compare the gyms by calculating and interpreting the average rates of change from
Week 1 to Week 3. From Week 1 to Week 3, Gym A membership increases at an average rate of _ people per week, and Gym B membership increases at an average rate of _ people per week. So, Gym _ membership is growing faster.
Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Step-by-step explanation:
To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
