Question
Mobile Provider A charges a $35 monthly fee plus $0.08 per minute for calls. Mobile Provider B charges a $25 monthly fee plus $0.14 per minute. What is an appropriate process to find when the two plans cost the same? Make two organized lists, one for the cost of Provider A and one for the cost of Provider B. Add values to the lists by multiplying $35.08 and $25.14 by the number of minutes used until the costs are the same. Make a table with two columns, one for Provider A and one for Provider B. For Provider A, start with a cost of $35 and multiply by $0.08 each time. For Provider B, start with a cost of $25 and multiply by $0.14 each time. Continue multiplying until the two columns are equal. Make a tree diagram with Provider A and Provider B as starting points, each with two branches. The base charges of $35 and $25 go at the ends of the branches for both. Then add 2 branches to the base charges. The per-minute costs go at the end of these branches. Add all the ends of the branches together. Make a graph with the number of minutes on the x-axis and the cost on the y-axis. For Provider A, start at 0 minutes and $35, and increase the cost $0.08 for every minute. For Provider B, start at $25, and increase the cost $0.14 for every minute. Continue both patterns until the plans have the same cost.
