Answer the following question.
Peter needs to buy birdseed to last a week. He knows that each parakeet eats 2 grams a day. His parrots eat 14 grams a day. His finches eat half of what a parakeet eats. If he has 3 parakeets, 2 parrots and 4 finches, how many grams of birdseed does he need to buy?
Step-by-step reasoning process: His parakeets eat 6 grams a day, because three parakeets times two grams each equals 6 grams. His parrots will eat 28 grams a day because two parrots times 14 grams equals 28 grams. Each finch will eat 1 gram a day, because they eat half of what a parakeet does and 1 / 2 of 2 equals one. His finches will eat 4 grams a day because four finches times 1 gram equals 4 grams. His birds eat 38 grams a day because 6 plus 28 plus 4 equals 38. Each week has 7 days. Therefore, in a week he will need 266 grams because 7 times 38 equals 266.
The answer is 266.

Answer the following question.
A farm is growing corn in 2 fields. One of the fields has 13 full rows of corn cobs, and the other field has 16 full rows of corn cobs. If each row contains 4 corn cobs, how many corn cobs has the farm grown?
Step-by-step reasoning process: In the first field, there are 13 rows * 4 corn cobs / row = 52 corn cobs. In the second field, there are 16 rows * 4 corn cobs / row = 64 corn cobs. So the farm has grown a total of 52 corn cobs + 64 corn cobs = 116 corn cobs.
The answer is 116.

Answer the following question.
In seven years, Talia will be 20 years old. Talia's mom is currently three times as old as Talia is today. In three years, Talia's father will be the same age as Talia's mom is today. Currently, how many years old is Talia's father?
Step-by-step reasoning process: In seven years, Talia will be 20 years old, and therefore Talia is currently 20 - 7 = 13 years old. Talia's mom is currently three times as old as Talia is today, or 3 * 13 = 39 years old. If in three years, Talia's father will be the same age as Talia's mom is today, then Talia's father is currently 39 - 3 = 36 years old.
The answer is 36.

Step-by-step reasoning process: There were 1 + 2 + 3 = 6 people at the house. That means they use 6 * 2 = 12 plates per meal. So they use 12 * 3 = 36 plates per day. That means they use 36 * 4 = 144 plates for the visit.
The answer is 144.
