Pedro's friend Chenetta is considering another text messaging plan that advertises the following: "A one-time joining fee of $3.00 and $0.08 per message."
Write an explicit formula for the text messaging plan.
Chenetta knows that she sends and receives 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.
