[Question]A local farmer is paying 4 kids to help plant rows of corn. Every row of corn contains 70 ears. A bag of corn seeds contains 48 seeds and you need 2 seeds per ear of corn. He pays the kids $1.5 per row. Afterward, the kids are so hungry that they end up spending half their money on dinner. The dinner cost $36 per kid. How many bags of corn seeds did each kid use?
[Answer]The dinner cost $144 dollars because 4 x 36 = 144. The kids earned $288 in total because 144 x 2 = 288. They planted 192 rows of corn because 288 / 1.5 = 192. They planted 13,440 ears of corn in total because 192 x 70 = 13,440. They each planted 3,360 ears of corn because 13,440 / 4 = 3,360. They each planted 6,720 seeds because 3,360 x 2 = 6,720. They each used 140 bags of seeds because 6,720 / 48 = 140. The answer is 140.

[Question]Dream's car consumes 4 gallons of gas per mile. If she drives 400 miles today and 200 more miles tomorrow than today, how many gallons of gas will the car consume?
[Answer]If she drives 400 miles today, the car will have consumed 4 * 400 = 1600 gallons of gas. Tomorrow, if she drives 200 more miles, the total distance will be 200 + 400 = 600 miles. The fuel consumption by the car tomorrow is 4 * 600 = 2400 gallons. The car's total fuel consumption in the two days is 2400 + 1600 = 4000 gallons. The answer is 4000.

[Question]Happy Island has 60 turtles. This means there are 10 more than 2 times as many turtles on Happy Island as on Lonely Island. How many turtles are there on Lonely Island?
[Answer]After subtracting 10 from the number of turtles on Happy Island, we get 60 - 10 = 50 turtles. Dividing this number by two, we find that the number of turtles on Lonely Island is 50 / 2 = 25 turtles. The answer is 25.

The first and last guard will take 3 + 2 = 5 hours of the night shift. There are 9 hours in the night shift, so the middle two guards will cover 9 - 5 = 4 hours. Each middle guard will take 4 / 2 = 2 hours. The answer is 2.
