Answer the following question.
An electronic shop offers smartphones for $300 each, personal computers for $500 more than smartphones, and advanced tablets for the sum of the prices of a smartphone and personal computer. How much do you have to pay to buy one of each of the three mentioned products?
Step-by-step reasoning process: The price of a personal computer is $300 + $500 = $800. The price of an advanced tablet would be $300 + $800 = $1100. To buy each of these products, you would have to pay $300 + $800 + $1100 = $2200.
The answer is 2200.

Answer the following question.
Jake and Penny are hunting snakes. Jake's snake is 12 inches longer than Jenny's snake. If the two snakes have a combined length of 70 inches, how long is Jake's snake?
Step-by-step reasoning process: Let j be the length of Jake's snake and p be length of Penny's snake. We know that j + p = 70, and j = p + 12. We can substitute the second equation into the first equation to get p + 12 + p = 70. Combining like terms, we get 2p + 12 = 70. Subtracting 12 from both sides, we get 2p = 58. Dividing both sides by 2, we get p = 58 / 2 = 29 inches. Penny's snake is 29 inches. Substituting that length in to the equation j = p + 12, we get j = 29 inches + 12 inches = 41 inches.
The answer is 41.

Answer the following question.
Frank bakes two trays of cookies per day, for 6 days. Frank eats one cookie each day to make sure they taste good. Ted comes over on the sixth day and eats 4 cookies. If each tray makes 12 cookies, how many cookies are left when Ted leaves?
Step-by-step reasoning process: Frank bakes 2 * 12 = 24 cookies per day. Frank bakes a total of 24 * 6 = 144 cookies. Frank eats 1 * 6 = 6 cookies. After Ted leaves, there are 144 - 6 - 4 = 134.
The answer is 134.

Answer the following question.
John decides to buy some birds. He got 50 dollars from each of his 4 grandparents. If each bird costs $20, how many wings did all the birds have?
Step-by-step reasoning process: He got 4 * 50 = $200. That means he was able to buy 200 / 20 = 10 birds. Since each bird has 2 wings he got 10 * 2 = 20 wings.
The answer is 20.
