Unit 1 – Item 4
A company is tracking the amount of revenue (in thousands of dollars) they generate each month.
The revenue can be modeled by the linear function 𝑓(𝑥) = 2𝑥 + 3, where 𝑥 is the number of months since the company started tracking.

If the company plans to track the revenue for the first 12 months, what is the domain of the function? Write your answer using interval notation.

…

Considering that the company projects a maximum revenue of $27,000 within this period, what is the range of the function? Write your answer using interval notation.

Unit 1 – Item 6
Danielle is analyzing the cost of internet service providers in New York. She is using a mathematical model where CCC represents the monthly cost and GGG is the number of gigabytes used. She has determined that the monthly cost for one provider is best modeled by a linear function.

Select the linear function that represents the monthly cost of the provider when the cost per gigabyte is $2.50 and there is a monthly fee of $20.

Unit 1 – Item 7
The school is organizing a charity fundraiser to support a local community project. Students are responsible for tracking the donations received each day and representing the data as an
arithmetic sequence.

On the first day of the fundraiser, the school received $500 in donations. Each subsequent
day, the donations increased by $75. Construct an arithmetic sequence function to represent the daily donations.

Unit 1 – Item 8
A beautician borrowed some startup money to start her business. She charges each client a set amount for her services. The total profit 𝑃(𝑐) she makes after 𝑐 clients can be modeled by a linear function. The function is given by 𝑃(𝑐) = 50𝑐 − 200, where 𝑃(𝑐) represents the profit in dollars after 𝑐 clients.

Part B:
A group of students studied the pattern. Each student has developed an equation that would be used to find the nth term in the sequence. Which student has an equation that works?

Model the Situation: Write a linear function 𝑓(𝑡) to represent the total amount of money in Jennifer's account after 𝑡 years.

Graph of the function 𝑓(𝑡). Identify the key
characteristics of the graph, including the y-intercept, slope, and the domain and range based on the context.

Analyze and Compare: Compare the linear function you wrote to the function 𝑔(𝑡) = 1000(1 + 0.05)𝑡, which represents a different savings plan where Jennifer starts with the
same $1000 but adds 5% interest compounded annually instead of adding a fixed amount
each year.

Calculate and Conclude: Determine how many years it will take for Jennifer to save
$28,000 to attend her favorite school using her original plan.

Calculate and Conclude: Determine how much money Jennifer will have in 6 years
under both plans
