Q1. Two boxes contain coloured bricks.

Box A contains 2 red bricks, 3 blue bricks and 1 yellow brick.

Box B contains 3 red bricks, 2 yellow bricks and 1 green brick.

Janet selects one brick from box A and one brick from box B.

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.
