Question: A bakery sells boxes of doughnuts and if there are any doughnuts left at the end of the day, the bakery gives them away. Each box of doughnuts holds 10 doughnuts and all of the doughnuts that the bakery makes are put into these boxes. The bakery makes 300 doughnuts for the day and sells 27 boxes of doughnuts throughout the day. How many doughnuts are given away at the end of the day?
Answer: The bakery has made 300 total doughnuts / 10 doughnuts per box = 30 boxes of doughnuts. So at the end of the day, they still have 30 total boxes of doughnuts 27 sold boxes of doughnuts = 3 boxes of doughnuts leftover. They are therefore giving away 3 boxes of doughnuts * 10 doughnuts per box = 30 doughnuts. The answer is 30.

Question: Laura wants to bake a cake for her mother. She checks the recipe and the pantry and sees that she needs to buy 2 cups of flour, 2 cups of sugar, a cup of butter, and two eggs. The flour costs $4. The sugar costs $2. The eggs cost $.5, and the butter costs $2.5. When she is done baking it, she cuts the cake into 6 slices. Her mother enjoys a piece the first two days. But on the third day, they discover that Kevin, her dog, ate the rest of the cake. How much did the amount the dog ate cost?
Answer: The cake cost $9 in total because 4 + 2 + .5 + 2.5 = 9. Each slice costs $1.5 because 9 / 6 = 1.5. The dog ate 4 slices because 6 - 2 = 4. The amount the dog ate cost $6 because 4 x 1.5 = 6. The answer is 6.
