Here is the pseudo code: START INPUT numOfPoster, type IF type = "colored" AND numOfPoster <= 500 payment = 2000 ELSE IF type = "colored" AND numOfPoster > 500 payment = 2000 + (numOfPoster - 500) * 2 ELSE IF type = "black and white" AND numOfPoster <= 500 payment = 1000 ELSE payment = 1000 + (numOfPoster - 500) * 1.5 PRINT payment END
