Question 1730
You want to make a 25 per cent profit..."PER CENT"..."per 100".."out of 100" ie 25 out of 100 is {{{25/100}}}

so, in English..what is 25% of 150?

in maths... what is {{{(25/100)*150}}}? Answer is 37.5.

So, this is the profit. So to make this profit, you would have to sell the item for 150+37.50 = 187.50.

Doing all this is condensed into the 1 line by the other tutor...but here is the explanation.

Try figuring out how to get to that one line answer from what i told you.

cheers
Jon.
