A certain item losses one tenth of its value each year if the item is worth birr 2800 today, how much will it be worth 4 year from now.
If the item loses one-tenth of its value each year, it means that its value decreases by 10% each year. Therefore, after one year, the item will be worth 90% of its current value (2800 * 0.9 = birr 2520).
To find out the value of the item after four years, we can multiply its current value by the percentage it retains each year:
Value after 1 year = 2800 * 0.9 = birr 2520
Value after 2 years = 2520 * 0.9 = birr 2268
Value after 3 years = 2268 * 0.9 = birr 2041.20
Value after 4 years = 2041.20 * 0.9 = birr 1837.08
Therefore, the item will be worth birr 1837.08 four years from now.
