Hi, Noted:  8 boxes sold on 2nd day

Let x represent  the total number of boxes of cookies

1st day sold (2/5)x  OR .4x

2nd day sold 8

question states***sold 45% of boxes the first two days

 .45x = .4x + 8

solving for x

   .05x = 8

      x = 8/.05

      x = 160 boxes, the total number of boxes of cookies

  55 % are left, there are .55*160 = 88 boxes left to sell
