I a working wth a cell phone performance task project. I have to determine which three cell phones are the best for a first time user and develop an equation for each of them.
Wal-Mart has a plan for $30.00 a month with .29 per minute. It includes a $70.00 phone with a rebate of $40.00 and a two year contract. Nextel has a plan for $28.00 a month plus $.30 per minute. With this plan you get a free phone and unlimited minutes with no contract. Carolina has a plan for $25.00 a month plus $.32 per minute. All roaming and long distance are free. You also get a phone for $19.99 with a one year contract.
How do I develop an equation that show the beginning of the first month and one that shows the equation after the first month.
I am stuck on the minutes. Please help!
A phone company has different payment plans for a cell phone. One of the plans charges a flat rate of $15 per month and 10 cents for every minute. Find a linear equation to model this plan.
