A photo of a container of popcorn is shown. The price tag reads one dollar and fifty cents.
He purchases a total of 150 containers of popcorn to sell. After he sells 15 containers, he will make a total profit, after his upfront costs, of $5.50. Cassidy’s profit, after upfront costs, can be modeled by a linear function in the form y=mx+b.
Question 1
Part A
What is the slope of the line that models the function?
Enter the correct answer in the box.
Question 2
Part B
How much were Cassidy’s upfront costs?
Enter the correct answer in the box
$$
Question 3
Part C
Will the function be discrete or continuous? Explain.
Continuous, because the profit increases continuously.
Discrete, because Cassidy sells whole containers of popcorn.
Continuous, because popcorn can fill fractions of a container.
Discrete, because the price of a container is constant.
Question 4
Part D
Write the function that models Cassidy’s profit.
Enter the correct equation in the box.
$\Sigma$
$x$$y$
Question 5
Part E
What is the domain of the function?
all whole numbers from 0 to 208
all real numbers from 0 to 208
all whole numbers from 0 to 150
all real numbers from 0 to 150
Question 6
Part F
What is Cassidy’s profit if he does not sell any popcorn?
Enter the correct answer in the box.
