х Which is the largest interval over which the function shown in the table is increasing? y=-x (x, y) -4 -8 (-4,-8) -2 -2 (-2,-2) 0 0 (0,0) -2. (2,-2) -8 (4, -8) 2 4 A. x < -2 0 B. x < 0 O C. X>0 O D. x > 2

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.
