Hi Bearbearian,

here's my solution to your 2nd question:

Note that I've changed the question from "in the end, Bala has twice as Ali..." to "in the end Ali had twice as much as Bala...." because this way it'll tally with the answer given

First of all, thank you for the solution on the 3rd question but on the 2nd question, I'm not clear on it.

I do not get the "1 1/2 unit = $54", could you explain on this please.

It's ok, I'll just have to draw the model step by step for better understanding.

Thank you for the time you spent helping.
