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 with step-by-step thinking: 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.
So the answer is 140.


Question: A 1000 car parking lot is divided into 3 sections. There are 320 spaces in section 1, and 200 more in section 2 than in section 3. How many spaces are made available in section 2 of the parking lot?
Answer with step-by-step thinking: There are a total of 1000 spaces - 320 spaces = 680 spaces in both sections 2 and 3. Let the number of spaces in section 3 be x. The number of spaces in section 2 = x + 200. We know that 320 + x + 200 + x = 1000. Combining like terms, we get 2x = 480. Dividing both sides by 2 produces x = 240. The number of spaces in section 2 is 240 + 200 = 440.
So the answer is 440.


Question: Emily is 20 years old and her older sister, Rachel, is 24 years old. How old is Rachel when Emily is half her age?
Answer with step-by-step thinking:
The difference in age between the two sisters is 24 - 20 = 4 years. When Rachel is twice Emily’s age, she is 4 x 2 = 8 years old.
So the answer is 8.
