Part A:
- Each dollar spent DOES appear to always have the same number of points.
This is correct because it has a set rate of 10 points per dollar.
- Predicted number of points spent for $9:
$9 * 10 = $90
Part B:
- It DOES appear to take the same amount of time to serve each customer.
This is correct because it has a set rate of 4 minutes per customer.
- Predicted number of customers served in 36 minutes: 36/4= 9 customers.
Hope this helps!
