Question and rationale: The question is: Phantom's mom gave him $50 to buy printer-inks. At the store, he bought two black printer inks which cost $11 each, three red printer inks which cost $15 each, and two yellow printer inks which cost $13 each. Phantom found out that his money is not enough to buy all the printer inks. How much more money should he ask his mom to be able to buy the printer inks?
Step-by-step reasoning process: Black printer inks will cost him 2 x $11 = $22. Red printer inks will cost him 3 x $15 = $45. And yellow printer inks will cost him 2 x $13 = $26. The total amount he has to pay for the printer inks is $22 + $45 + $26 = $93. Therefore, Phantom has to ask $93 - $50 = $43 more from his mom to be able to buy the printer inks.

Question and rationale: The question is: There are five times as many swordfish as pufferfish in an aquarium exhibit. If there are 90 fish total, how many pufferfish are there?
Step-by-step reasoning process: Let s be the number of swordfish and p be the number of pufferfish. We know that s = 5p and s + p = 90. Substituting the first equation into the second equation, we get 5p + p = 90. Combining like terms, we get 6p = 90. Dividing both sides by 6, we get p = 15.

Question and rationale: The question is: After receiving the $2000 stimulus check, Mr. Eithan decided to share the amount with his family. He gave 2/5 of the amount to his wife, 2/5 of the remaining amount to his first son, 40% of the remaining amount to his second son, and kept the remaining in their family savings account. Calculate the total amount he kept in the family's savings account.
Step-by-step reasoning process: The total amount of money Mr. Eithan gave to his wife is 2 / 5 * 2000 = $800. After giving his wife $800, he remained with $2000 - $800 = $1200. He gave his first son 2 / 5 of the remaining amount which is 2 / 5 * $1200 = $480. The total amount remaining after he gave his first 2 / 5 of the amount is $1200 - $480 = $720. He then gave his second son 40 / 100 * 720 = $288 of the money. After giving his second son $288, the amount of money remaining that he saved in the family's saving account is $720 - $288 = $432.

Question and rationale:
The question is: Apple sold 100 iPhones at their New York store today for an average cost of $1000. They also sold 20 iPads for an average cost of $900 and 80 Apple TVs for an average cost of $200. What was the average cost across all products sold today?
Step-by-step reasoning process: The sales for iPhones were 100 iPhones * $1000 per iPhone on average = $100,000. The sales for iPads today were 20 iPads * $900 per iPad = $18,000. The sales for Apple TV’s today were 80 * $200 = $16,000. The total sales for Apple at their New York store today was $100,000 + $18,000 + $16,000 = $134,000. The total number of products sold was 100 + 20 + 80 = 200. The average cost per product sold was $134,000 total sales / 200 total products = $670.
