13. 8d - 10 = 4(2d - 6) 
      8d - 10 = 8d - 12
      8d - 8d = -12 + 10
       0 = -2......incorrect....NO SOLUTIONS

14. 3.50c > = 500
      c > = 500/3.50
      c > = 142.857....she can sell (minimum) of 143

15. 14c - 10 = 20
      14c = 20 + 10
      14c = 30
         c = 30/14 reduces to 15/7 (or 2 1/7)

16. c = 1.50g + 3
