Okay, so here we have a $40,000 car and it leaves with loses half of its value every year. That's 50%. It loses every year. So we want to see what at the end of six at at six years. How much is it worth? Okay. So rather easy, you could just do it almost in your head. So 40,000 is the first year. Second year. It's half of that, which is 20,000. That's this is the first year, first year, second year. It's 10,000. It's half of that. That 2nd 3rd year. It's 5000. Fourth year. It's half of that, which is 2500 50 years, half of that. So this one's gonna be 1 12 50 That's the fifth year in the six year is half of that, which is 6 25 after six years. Half it decreases by happy each time. It's only gonna be
