Yоu mоved tо а new house in Jаnuаry 2024 and are worried about your high electricity bills. You asked a Solar Panels installer to make you a proposal for installing a new Solar system. Your electricity bills for 2024 were as follows: Month Electricity Period Feb-24 500 2 Apr-24 350 2 May-24 300 1 Jun-24 350 1 Jul-24 200 2 Sept-24 150 1 Nov-24 350 2 The December bill is still unavailable, and since you have changed electricity suppliers, some of your bills correspond to 1 or 2 months, as indicated in the column period. The Sollar company's quote says you will need to pay 12 500€ for your new Sollar Pannels, but it will be fully paid in 5 years, considering that you can decrease your electricity bills to zero. Taking into account that you have 12 500€ in a bank account receiving an interest rate of 1% APR and that you estimate that the inflation rate for the price of electricity will be 2% for the next 5 years. Requested: a) Should you make this investment? 20 Marks b) Is the installer lying to you, or did he forget a basic rule in Finance? 5 Marks Total: 25 Marks
