milly has a 12m length of matirial, she uses four lengths of 2.3m to make curtains ,she uses the rest to make cushions, a cushion needs a length of 0.48m of the matirial, how many cushions can she make??

true? is that what you're asking or do you mean something else?

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
