Q2. A painting was valued at £600 on 1 January 2004.
The value of the painting is predicted to increase at a rate of R% per annum.
The predicted value, £V, of the painting after n years is given by the formula
V = 600 × (1.055)^n
Use your calculator to find the predicted value of the painting after 15 years.
