A software developer recently launched a new social media app
and is concerned about user retention (i.e., users continuing to
use the app after initial download). In order to study the retention
of users, the company looked at users who shared three or more
pictures on the app within the first five days of downloading the
app (Group A, which is indicated by the solid line in the graph
below) and compared the use of the app by these users in the
days following the initial download with the use of the app in the
days following the initial download by users who did not share
,Page 2 of 31
three or more pictures on the app within the first five days after
downloading the app (Group B, which is indicated by the dashed
line in the graph below). The data in the graph shows the
retention rates for these two groups, where t is the number of
days since the initial download of the app, and y is the
percentage of users who still use the app
The retention rates of both Group A and Group B stabilize as time
increases and appear to have different asymptotes.
A company's total monthly cost is given by the linear function C(
x) = 11,000 + 550 x , where C is the total monthly cost and x is the
number of units produced each month. The graph of the function
is given below: What does the y-intercept represent in this
situation?
If 0 items are produced, the monthly cost is $11,000.00.
A cable company, a satellite dish company, and a streaming
service all offer TV viewing plans based on the number of
channels, c, on the plan. The price of each plan is given below:
Cable: P( c) = 3 c + 60Satellite dish: P( c) = 4 c + 35Streaming
service: P( c) = 5 c + 50 Which company's cost per additional
channel is most expensive?

The number of gym memberships since January 1, 2015, for a
particular gym is given by the function N( x) = 100 + 11 x, where N
is the number of gym members x months after January 1, 2015.
How can the slope be interpreted?
Each month, 11 members join the gym.
The pricing models of four contractors are given below, where t
is the number of hours worked and P is the total cost of the job.
Contractor A: P( t) = 100 + 20 tContractor B: P( t) = 99 + 25
tContractor C: P( t) = 50 + 35 tContractor D: P( t) = 80 + 25 t Which
contractor gives the cheapest hourly rate?
Contractor A
An appliance manufacturer has determined that the profit, P( x),
that it makes in manufacturing and selling x dishwashers can be
determined from the function in the graph below. How many

dishwashers must the company manufacture and sell in order to
make a profit of $80,000?
130
The profit function P( x) gives a company's total profit (in millions
of U.S. dollars) for x products produced (in thousands). The graph
of P( x) is below: At which number of products produced does the
company stop being profitable?
About 4,500 items
A big box store found its number of customers, C, in thousands
on Saturday is predicted by the time of day in hours, t. In the
graph below, t = 0 corresponds to midnight of the current day and

average rate of change from t = 8 to t = 10 be interpreted?
There are, on average, 1,000 more customers per hour.
