1) I have managed to created two 2D Tables for each of the companies (Supreme and Goldee). Where it shows the computed price of both
independent clause ( Rental Price of Car and Total Travelling Cost depending on Days)

2) Right now i am currently trying to plot a graph to serve as a presentation of the break even point where Supreme is better than Goldee over time. However, after searching on youtube and google i can'ts seem to find a guide on how to make a single graph from two 2D Tables

3) Lastly would it be better to use Goal Seek/ Solver to proves the the last 2 question which is (At what travel distances will you be indifferent to either rental company?)
