Hi, please help

Thanks Adwin.

Please correct me if I’m wrong. The question asks for the money they gave away altogether, not individually. So, isn’t it 20 units instead of 10 units? If that’s the case, shouldn’t the answer be $360?

Kindly advise and thanks.

Regards,

KK

Yes. You are correct. That’s a mistake on my part.

I have previously tried to resolve the same problem but with no success. That is why I found the website where I can pay someone to do my assignment in Australia, and the guys from this website www.essayontime.com.au/ helped me a lot with my task.
