Let's set it up as a ratio

256 is to 10%   as   x is to 100%

256/10  =  x/100      solve for 'x'

x= $2560        amount he earned for the summer

10% = 10/100 or 1/10

 

so basically if he gives away $256 then 256 is 1/10th of the money he earnt so the amount of money he earnt is 256*10 = $2560. peace.cool
