Step-by-step explanation
Linear functions have the form,
![f(x)=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/6o509bhbp213rd8y4ne1d5fl5x7nzt1y7d.png)
Where m is the slope - or growth rate, and b is the y-intercept - or initial value.
For this problem, the cost of the movies is a linear function where the initial value is $11 and the slope is $4.99. Thus, the cost of the ordered movies m is,
