Modeling Cell Phone Plans with Functions

The video tutorial explains how to model a cell phone plan that charges a base fee and an additional cost per gigabyte of data used. The instructor guides viewers through creating a mathematical function to represent this scenario, detailing the variables involved. The video concludes with a call to action to subscribe and download additional resources.

What is the fixed monthly cost of the cell phone plan?

• $20

• $30

• $50

• $25

How much does the plan charge per gigabyte of data used?

• 25 cents

• 50 cents

• 75 cents

• 1 dollar

What does the variable 'X' represent in the function?

• The monthly cost

• The number of gigabytes used

• The total data cost

• The fixed monthly fee

If no data is used in a month, what would the total bill be?

• $12.50

• $25

• $0

• $50

What would the monthly bill be if 1 gigabyte of data is used?

• $25.50

• $28

• $27

• $26

What is the purpose of the function created in the video?

• To determine the monthly bill based on data usage

• To calculate the total data used
