A car's value depreciates by 15% each year. If bought for $30,000, what is its value after 3 years?

Jawaban: $18,500

Value = 30000×(0.85)³ = 30000×0.614125 = 18423.75, closest to $18,500? Actually 18,423.75 rounds to 18,424, not exactly options. So maybe 30000*0.85³ = 18423.75, so none exactly. But if 15% depreciation: year1:25500; year2:21675; year3:18423.75. So option $18,500 is not exact. So maybe use 20%? Then 30000*0.8³=15360. Not. So this question is flawed. Let's change numbers: depreciates 10% each year, after 3 years: 30000*0.9³=21870, not. Or 20%: 15360. So maybe use simple interest? Better to replace with a different problem.
