If you buy a dozen of doughnuts, it costs $8; but if you buy 2 dozens, it costs $14. How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen?

How much does 6 sets of 1 dozen cost? ** Six sets of 1 dozen of doughnuts cost $8 x 6 = $<<6*8=48>>48.
How much does 3 sets of 2 dozens cost? ** Three sets of 2 dozens of doughnuts cost $14 x 3 = $42.
How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen? ** Therefore, you can save $48 - $42 = $<<48-42=6>>6.
