Ratio (sharing an amount among 3 people)

[Natasha1]

Homework Statement:

Andreas, Isla and Paulo share some money in the ratios 3:2:5. The total amount of money that Isla and Paulo receive is £76 more than the amount of money that Andreas receives. Andreas buys a video game for £48.50 with some of his share of the money. Work out how much money Andreas has left from his share of the money when he has bought the video game.

Relevant Equations:

3+2+5 = 10 parts

So 7 parts is worth £76 more than 3 parts which means that

4 parts = £76

So 1 part = £19

Therefore Andreas gets £57, Isla gets £38 and Paulo gets £95.

So Andreas has £57 - £48.50 = £8.50 left

Is this correct please?
