Sarah's current mobile phone plan is about to end. She is currently with Telstra and has 80 GB of data left. She is deciding between two options: Option 1: Continue to recharge with Telstra. If she chooses this option, the 80 GB of data left rolls over into the next recharges. Telstra $50 Pre-paid SIM Telstra SIM-Only-Prepaid all Telstra 40 network Optus $50 Pre-paid SIM OPTUS 50 GB Data Option 2: Change to Optus which offers more data at the same price, but does not roll over the 80 GB of data she has left. SIM-Only-Prepaid il Optus 4G network $50 per 28 days expiry 60GB Data@ $50 per 28 days expiry Go to site For both prepaid plans, she does not enable auto-recharging. A) Let m represent the number of months that Sarah recharges her prepaid plan and Dr represent the amount of mobile data available after each recharge with Telstra. Using these variables, write an equation that shows the relationship between the number of recharges and data available if Sarah continues to recharge with Telstra. B) Let m represent the number of months that Sarah recharges her prepaid plan and DO represent the amount of mobile data available after each recharge with Optus. Using these variables, write an equation that shows the relationship between the number of recharges and data available if Sarah changes to Optus to recharge C) Use Desmos graphing calculator or an equivalent graphing technology to graph the equations from Section 2 Questions A and B on the same axes.Label the axes with the appropriate variables and the point of intersection of both graphs.Adjust the scale to show the possible values for m and D in this problem.
