Factor the sum of terms as a product of the gcf and a sum 52 +28

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.

333.74 ! should be your answer for this question

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
