i am trying to calculate the selling price, and think i am missing something really simple... i have the answer for the first one but that is as far as i have got. but i just need the equation (or the way to do it)

so...

if the cost price is £2.50 and the GP is 60% what is the selling price = 7.34

i just dont kniow how i got that answer

Help please
