Drawing a depreciation graph

A car is worth £16 000 when new. Its value falls by 25% each year, so its value after \(t\) years is \(V=16\,000\times0.75^{t}\) pounds.

1. Complete the table, giving values to the nearest £10.

   \(t\)	0	1	2	3	4	5
   \(V\)	16 000	12 000

2. Draw the graph of \(V\) against \(t\) for \(0\le t\le5\).
3. Use your graph to estimate the time when the car is worth £8000.
