Step-by-step reasoning process: The cost of the pots is 3 * $20 = $60. The cost of 4 pans is $100 - $60 = $40. Since each pan is the same price, the cost of 1 pan is $40 / 4 = $10. The cost of 2 pans is $10 + $10 = $20.
[Q & A] The question is Katerina purchases 3 pots and 4 pans at the home goods store. Each pot costs $20. The total cost of Katerina's items is $100. If each pan is the same price, what is the cost of 2 pans?
The answer is 20

Step-by-step reasoning process: Lyka has to save a total of $160 - $40 = $120 for two months. There are 2 x 4 = 8 weeks in two months. Hence, Lyka needs to save $120 / 8 = $15 per week.
[Q & A] The question is Lyka wants to buy a smartphone worth $160 but she only has $40 at the moment. She plans to save an equal amount of money per week for two months for the remaining amount that she needs. How much should she save per week?
The answer is 15

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.
[Q & A] The question is 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?
The answer is 4

Step-by-step reasoning process: Two boxes of crayons have 24 x 5 / 8 = 15 unused crayons from each box. So, a total of 15 x 2 = 30 unused crayons are in the two boxes. For the other 2 boxes, there are 24 x 2 / 3 = 16 used crayons from each box. Hence, there are 24 - 16 = 8 unused crayons. So, a total of 8 x 2 = 16 unused crayons are in the other two boxes. Therefore, Madeline has a total of 30 + 16 + 24 = 70 unused crayons.
[Q & A]
The question is Madeline has 5 boxes with 24 crayons in each. She noticed that 5/8 of the crayons in the 2 boxes were not yet used. In the 2 other boxes, only 2/3 of the crayons were used while the last box was not entirely used. How many unused crayons did Madeline have?
The answer is 70
