We have been given the equation
It represents the number of people standing to catch a commuter train x hours after 5 A.M.
Now, in order to find the number of people in line at 7 a.m. , we need to substitute x= 2 in the above equation.
Therefore, the number of people in the line at 7 a.m. is 40
D id the correct option.
Answer:
The percent increase per year is 4%
Step-by-step explanation:
we have
This is a exponential function of the form
where
y represent the monthly rent at Lake View Apartments
x represent the number of years
a is the initial value (y-intercept)
b is the base
r is the rate or percent increase
The percent increase per year is the base of the exponential function decreased by 1.
so
In this problem we have
---> initial value
Therefore
The percent increase per year is 4%
