Q: 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?
A: 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.

Q: Isaac cut his 30 meters ribbon into 6 equal parts. He then used 4 parts of the ribbon. How many meters of ribbon are not used?
A: Each part is 30 / 6 = 5 meters long. Since Liam used 4 parts, then he used 5 x 4 = 20 meters of the ribbon. So, 30 - 20 = 10 meters of ribbon is not used. The answer is 10.

Q: Matilda had 20 chocolate bars and shared them evenly amongst herself and her 4 sisters. When her father got home from work, he was upset that they did not put aside any chocolates for him. They felt bad, so they each gave up half of their chocolate bars for their father. Their father then gave 3 chocolate bars to their mother and ate 2. How many chocolate bars did Matilda's father have left?
A:
Matilda and her sisters each got 20 chocolate bars / 5 people = 4 chocolate bars / person. They each gave 4 / person / 2 = 2 chocolate bars / person to their father. Their father received 2 chocolate bars / person x 5 people = 10 chocolate bars. Their father had 10 chocolate bars - 3 chocolate bars - 2 chocolate bars = 5 chocolate bars left. The answer is 5.
