Pedro is planning to add a text message feature to his cell phone plan. He has gathered information about the two different plans offered by his wireless phone company. Plan A: $4.00 per month plus 4 cents for each message
Plan B 5 center per message
1. Use the mathmatics you have been studying in this math unit to provide Pedro with the following information for each plan.
Plan A
a table of data
a graph of the data
the linear function that fits this plan
the domain and range of the function
Plan B
a table of data
a graph of the data
the linear function that fits this plan
the domain and range of the function
2 If Pedro sends 360 messages on average each month, which plan would you reccomend that he chooses? Support your recommendation using mathematical evidence.
3 If Pedro knows that his average usage is going to increase to 500 text messages per month, should he change to a different plan? Explain and justify your reasoning.
4 Explain whether either of the plans represents a direct variation.
5 Pedro's friend Chenetta is considering another text message plan that advertises the following: "A one-time joining fee of $3.00 and $0.08 per message."
a Write an explicit formula for the text messageing plan.
B Chenetta knows that she sends and recives about 1800 text messages per month. Use an example and other mathematical evidence to let Chenetta know if you think this plan would be a good deal for her.
