Question

Thianga buys a car for $75 000. The value of the car depreciates at 15% per year. After 1 year the car is worth 85% of its original value.

How many years will the car be worth less than $15000? without using log

Answer 1

Answer: 6 years

Explanation:

75,000*15% = 11,250

11,250*6 = 67,500

75,000-67,500 = 7500

7500 is worth less than 15,000

5 years would have been 18,750; more than 15,000
