Hi,
8 cents for every problem{{{highlight(x)}}} in this chapter that you solve correctly 
and fine you 5 cents for every problem{{{highlight(y)}}} done incorrectly.
Question states*** 
  x + y = 26  0r  {{{x = 26-y}}}
 8x - 5y = 0
8(26-y) - 5y = 0
   208 = 13y
    16 = y, solved incorrectly.  10 solved correctly
and...
 {{{8*10 - 5*16 = 0}}}
