Final answer:
After 2 years, the computer Mr Singh bought for £2500, with an annual depreciation rate of 7.2%, is worth approximately £2149.76.
Step-by-step explanation:
Mr Singh buys a computer for £2500, and each year the value of the computer depreciates by 7.2%. To calculate how much the computer is worth after 2 years, we need to apply the depreciation formula twice, once for each year.
After the first year, the computer's value will be:
Value after 1 year = Initial value × (1 - depreciation rate)
Value after 1 year = £2500 × (1 - 0.072) = £2500 × 0.928 = £2320
After the second year, the computer's value will further depreciate by another 7.2%:
Value after 2 years = Value after 1 year × (1 - depreciation rate)
Value after 2 years = £2320 × (1 - 0.072) = £2320 × 0.928 = £2149.76
Therefore, after 2 years, the computer is worth approximately £2149.76.
