You are in the market for a used car in Egypt, and you find one that you like for \(\mathrm{E} £ 210,000\) at a local dealership. The dealer offers you a choice in paying for it: a discount of \(E £ 15,000\) if you pay the full amount immediately or a \(E £ 42,000\) down payment plus zero percent financing of the balance, paid annually over four years, if you pay by credit (that is, equal payments of \(E £ 42,000\) at the end of each year for the next four years). If your discount rate is \(4 \%\), which payment option should you choose?
