[Question]: Phillip's mother asked him to go to the supermarket to buy some things and gave him $95, so he spent $14 on oranges, $25 on apples and $6 on candy. How much money does he have left?
[Answer]: If we add everything Phillip bought, we will have: $14 + $25 + $6 = $45. He spent $45, and we know that he had $95 dollars, so now we have to subtract: $95 - $45 = $50.
So the answer is 50.

[Question]: 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?
[Answer]: Six sets of 1 dozen of doughnuts cost $8 x 6 = $48. Three sets of 2 dozens of doughnuts cost $14 x 3 = $42. Therefore, you can save $48 - $42 = $6.
So the answer is 6.
