Beyond the Answer
Let the shares of Andreas, Isla, and Paulo be represented by \( 3x \), \( 2x \), and \( 5x \) respectively. The total amount received by Isla and Paulo is: \[ 2x + 5x = 7x \] According to the problem, Isla and Paulo's combined amount is \( £76 \) more than Andreas's amount: \[ 7x = 3x + 76 \] Solving for \( x \): \[ 7x - 3x = 76 \\ 4x = 76 \\ x = 19 \] Now we can calculate how much money each person receives: - Andreas: \( 3x = 3(19) = £57 \) - Isla: \( 2x = 2(19) = £38 \) - Paulo: \( 5x = 5(19) = £95 \) Andreas spends \( £48.50 \) on a video game. To find how much money he has left: \[ £57 - £48.50 = £8.50 \] Thus, the amount of money Andreas has left after buying the video game is \( £8.50 \).
