Consider the Q and A. Q: Alissa used discarded paper to make notepads for her friends. She would fold 5 pieces of letter-size paper 3 times then cut along the edges to form smaller note papers. She would then stack these smaller note papers and staple them together. How long would 1 notepad last if someone wrote 10 notes per day?
A: 4
What is the step-by-step reasoning process?
Step-by-step reasoning process: Alissa folding it 3 times makes 2 2 2 = 8 pieces of note - size paper per letter - size paper. So 5 pieces of letter - size paper make 5 8 = 40 pieces of note - size paper. 1 note pad would last 40 10 = 4 days if someone wrote 10 notes a day.

Consider the Q and A. Q: Mary has 300 sheep and Bob has double the number of sheep as Mary plus another 35. How many sheep must Mary buy to have 69 fewer sheep than Bob?
A: 266
What is the step-by-step reasoning process?
Step-by-step reasoning process: Bob has (300 * 2) + 35 = 635 sheep. For Mary to have 69 sheep fewer than Bob she must own 635 69 = 566 sheep. As Mary has already 300 sheep she must buy 566 300 = 266 sheep.

Consider the Q and A. Q: Reese has been practicing piano for four hours every week. How many hours will he practice after five months?
A: 80
What is the step-by-step reasoning process?
Step-by-step reasoning process: If Reese practices 4 four hours every week, in a month, with four weeks, he would have practiced for 4 * 4 = 16 hours. In five months, Reese would have practiced for 5 * 16 = 80 hours.

Consider the Q and A. Q: Janice adds 2 tablespoons of koolaid power and 16 tablespoons of water to a jug. She leaves it out long enough for 4 tablespoons of water to evaporate. Then she quadruples the amount of water in the jug. What percentage of the liquid in the jug is koolaid powder?
A: 4
What is the step-by-step reasoning process?
Step-by-step reasoning process:
First find how many tablespoons of water are left after the evaporation: 16 tbs - 4 tbs = 12 tbs. Then multiply this number by 4 to find how much water is in the jug after Janice refills it: 12 tbs * 4 = 48 tbs. Now add the 2 tablespoons of koolaid powder to find the total volume of the liquid in the jug: 48 tbs + 2 tbs = 50 tbs. Now divide the volume of the koolaid powder by the total volume and multiply by 100% to find the percentage of the liquid that's koolaid: 2 tbs / 50 tbs * 100% = 4%.
