A) C= 1.08p - 0.15p
B) C= 1.15p + 0.08p
C) C= 1.08(0.85p)
D) C= 0.85p + (0.08)0.85p
E) C= p- 0.15p + 0.08p

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.
