Lets say your cell phone bill is $50 per month, plus a variable charge of $0.40 per minute if you go over 700 minutes. Lets also say that your June 2017 bill just arrived and is $100.00 total (ignore taxes).
1. What would the equation look like? Write out the equation for a straight line please and then write the equation again with the numerical values in the equation.
2. How many total minutes did you talk in June 2017?
3. How much would your total cell phone be if you were to talk 900 minutes? How about 1,200 minutes?
