Rosa bought some 18 cent stamps and some 32 cent stamps,paying a total of $4.28. There were four more 32 stamps than 18cent stamps. How many did she buy of each?

Explanation / Answer

A = # of 32 cent stamps B = # of 18 cent stamps A + 4 = B    (four more 32 stamps than 18stamps) .32A + .18B = 4.28   (32 cents * A # of stamps + 18 cents* B # of stamps = 4.28)
