Problem description Pavel wants to buy a new car. He is intrigued by a 100% electric car, so he did a bit of research to compare two models, one being a petrol (P) and the other one being an electric (5) model. The table below shows the summary of all the relevant cost figures. Model Retail Price Car Tax (per year) Plug-in Car Grant EO Insurance (per year) 280 Servicing (per year) 180 Fuel (per km) 0.075 Residual Value E7,000 P 15,000 130 E 25,000 5,000 ED 320 110 0.025 8,500 Residual Value is the value of the car after three years since Pavel wants to compare the costs over a 3-year period. To simplify calculations, Pavel assumed no time value of money and came up with the following expression for the total cost (in ) of Model E: E = 25,000 - 5,000 + 3x (0 - 320 + 110) +0.025 x "km travelled in 3 years" - 8,500 Part A (20%) Use variable x instead of "km travelled in 3 years and simplify the expression for the total cost of Model E. Also, formulate and simplify the total cost of Model P. YOUR ANSWER: (if answering through the text box) Selected Answer: ex 12790+0.025x 25000-5000=20000 3x (0+320+110)-1290 20000+1290-21 290-8500-12790
