My first post here. I hope I am posting this question in the right place
I need help with a problem and it goes something like this:
A man is selling soda. He has two types of bottles for sale: One that contains 1 litre and one that contains three litres.
The bottles that contains one litre costs 50 money
The bottle that contains three litres costs 130 money
When the day is over he has sold bottles for 9240 money. He sold a total of 100 bottles.
How many litres has he sold?
English is not my first language, but i hope you understand anyway
