Simon bought a 48$ dollar table on sale for 30 percent off

I'm pretty sure this is the answer. 43 / (30%) = 143.33 Hope this helps.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
