Given
- Brian buys a computer for £2100.
- It depreciates at a rate of 1% per year
To Find
- price after 6 years
Solution
price after 6 years = P ( 1 - R/100 )⁶
→ price after 6 years = £2100 ( 1 - 1/100 )⁶
→ price after 6 years = £2100 ( 99/100 )⁶
→ price after 6 years = £2100 ( 0.99 )⁶
→ price after 6 years = £2100 × 0.941
→ price after 6 years = £1976.2
price after 6 years is £1976.2
