Hi

8 fewer breast cancer stamps than the number of regular stamps

Let x and (x-8)represent the number of regular and bc stamps respectively

Question states***Note: CENTS makes sense

 37x + 40(x-8) = 1990

Solving for x

  77x = 2310

       x = 30, the number of regular and  22 breast cancer stamps  (30-8)

  37*30 + 40*22 = 1990 or $19.90
