Answer 1

someone please help me :/

Answer 2

Hey let number of 1 cent stamps= A,
32cent stamps= B
33 cent stamps= C
then form equations...
*1 cent stamps,32 cent stamps, and 33 cent stamps for $21.80(= 2180 cents)*
gives A + 32B + 33C = 2180

* number of 1 cent stamps exceed the number of 33 cent stamps by 50* gives
A = C+ 50 ..................... (1)

*number of 32 cents was 10 less than twice the number of 33 cents stamps* gives
B= 2C-10 ......................(2)
Now use equation (1) and (2) in above...Hope this helps...
