Answer the following question.
Clara is selling boxes of cookies to raise money for a school trip. There are 3 different types for sale. The first type has 12 cookies per box. The second type has 20 cookies per box, and the third type has 16 cookies per box. If Clara sells 50 boxes of the first type, 80 boxes of the second type, and 70 boxes of the third type, how many cookies does she sell?
Step-by-step reasoning process: Clara sells 600 cookies of the first type because 12 * 50 = 600. She sells 1600 cookies of the second type because 20 * 80 = 1600. She sells 1120 cookies of the third type because 16 * 70 = 1120. Thus, Clara sells 3300 cookies total because 600 + 1600 + 1120 = 3320 cookies.
The answer is 3320.

Answer the following question.
If 3 crows eat 30 worms in one hour, how many worms will 5 crows eat in 2 hours?
Step-by-step reasoning process: If 3 crows eat 30 worms in one hour, then each crow eats 30 / 3 = 10 worms per hour. 5 crows will eat 5 * 10 = 50 worms per hour. Over two hours, 5 crows will eat 2 * 50 = 100 worms.
The answer is 100.

Answer the following question.
There are 285 sweets in the bowl. If 49 of the sweets are red and 59 of the sweets are green, how many of the sweets are neither red nor green?
Step-by-step reasoning process: There are 49 + 59 = 108 red or green sweets in the bowl. There are 285 - 108 = 177 sweets that are neither red nor green.
The answer is 177.

Answer the following 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?
Step-by-step reasoning process: 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.
The answer is 6.
