Beyond the Answer
Let's denote the shares of Andreas, Isla, and Paulo as \( 3x, 2x, \) and \( 5x \) respectively. According to the problem, the total amount received by Isla and Paulo is £76 more than Andreas' share. We can express this as: \[ 2x + 5x = 3x + 76 \] This simplifies to: \[ 7x = 3x + 76 \] Subtracting \( 3x \) from both sides, we get: \[ 4x = 76 \] Dividing both sides by 4, we find: \[ x = 19 \] Now we can calculate how much money each person receives: - Andreas: \( 3x = 3 \times 19 = £57 \) - Isla: \( 2x = 2 \times 19 = £38 \) - Paulo: \( 5x = 5 \times 19 = £95 \) Next, we determine how much money Andreas has left after buying the video game for £48.50: \[ \text{Money left} = 57 - 48.50 = £8.50 \] So, Andreas has £8.50 left from his share of the money after buying the video game.
