Game Money Exchange

Hello.

So I sold £20 worth of games for £8. So how much would £12 worth of games sell for?

3.50

Eh, 4.80 assuming the ratio is supposed to be the same as the first example?

homework question in disguise

Dude my bro is a mathematician and he said 4.80

So I'll get £5 basically.

Doesn't take a mathematician to figure that out, but congratulations
