Answer the following question.
Nate got lost looking for his car in the airport parking lot. He had to walk through every row in Section G and Section H to find it. Section G has 15 rows that each hold 10 cars. Section H has 20 rows that each hold 9 cars. If Nate can walk past 11 cars per minute, how many minutes did he spend searching the parking lot?
Step-by-step reasoning process: First find the number of cars in Section G by multiplying the number of rows by the number of cars per row: 15 rows * 10 cars / row = 150 cars. Then do the same thing for Section H: 20 rows * 9 cars / row = 180 cars. Then add the two quantities of cars to find the total number of cars Nate walked past: 150 cars + 180 cars = 330 cars. Finally, divide the number of cars Nate passed by the numbers he passes each minute to find how long he spent searching: 330 cars / 11 cars / minute = 30 minutes.
The answer is 30.

Answer the following question.
While cultivating a small farm, a farmer spent $50 on corn seeds, $35 on fertilizers and pesticides, and $15 on labor. After a successful harvest, he was able to gather 10 bags of corn. How much should he sell each bag, if he wants to make a profit of 10%?
Step-by-step reasoning process: His total expenditure so far is $50 + $35 + $15 = $100. To make a profit of 10%, he has to make a total of $100 + ($100 * (10 / 100) = $110 from sales. To make $110 from the sales of 10 bags, each bag should cost $110 / 10 = $11.
The answer is 11.

Answer the following question.
The Arevalo family went out to dinner. The smoky salmon costs $40, the black burger costs $15, and the chicken katsu costs $25. If the bill includes a 10% service charge and 5% tip, how much change will Mr. Arevalo receive from his $100?
Step-by-step reasoning process: The total amount spent on food is $40 + $15 + $25 = $80. The service charge is $80 x 10 / 100 = $8. The tip is $80 x 5 / 100 = $4. So, Mr. Arevalo had to pay $80 + $8 + $4 = $92 in all. Therefore, his change will only be $100 - $92 = $8.
The answer is 8.
