Question: Emma bought a loaf of bread that had a certain number of slices. Her little cousin Andy ate 3 slices from the bread at two different points in time, and then Emma decided she would make toast with the remaining slices. If she uses 2 slices of bread to make 1 piece of toast bread, how many slices were in the original loaf if she was able to make 10 pieces of toast bread and had 1 slice of bread left?
Answer: Step-by-step reasoning process: Little Andy ate 3 slices 2 times giving a total of 3 * 2 = 6 slices of bread. 1 piece of toast bread requires 2 slices of bread so 10 pieces need 10 * 2 = 20 slices of bread. There is 1 slice of bread left so in total there were 6 + 20 + 1 = 27 slices of bread in the loaf.
So the answer is 27.

Question: Johnny is buying planks of wood to build some tables. Each table needs a plank of wood for each of the legs and 5 planks of wood for the surface. If Johnny wants to build 5 tables, how many planks of wood does he need?
Answer: Step-by-step reasoning process: Each table needs 1 plank of wood * 4 legs = 4 planks of wood for the legs. This means each table needs 4 planks of wood for legs + 5 planks of wood for the surface = 9 planks of wood. To build 5 tables, Johnny will therefore need 9 planks of wood * 5 tables = 45 planks of wood.
So the answer is 45.

Question: Alexa and Emily open up a lemonade stand in the front yard. They spent $10 for lemons, $5 for sugar and $3 for cups. The lemonade is $4 a cup. They sell a total of 21 cups. How much profit did Alexa and Emily make after paying off expenses?
Answer: Step-by-step reasoning process: Alexa and Emily spend a total of $10 + $5 + $3 = $18. They make a total of $4 x 21 = $84. They make a profit of $84 - $18 = $66.
So the answer is 66.

Step-by-step reasoning process: First find the value of the 2 cards Matt trades: $6 / card * 2 cards = $12. Then find the total value of the 3 $2 cards: 3 cards * $2 / card = $6. Then subtract the value of the cards Marcus gave up from the value of the cards he gained to find his profit: $9 + $6 - $12 = $3.
So the answer is 3.
