Step-by-step reasoning process: Currently, Kate has only 1 / 3 * 30 = $10. That means Kate needs 30 - 10 = $20 more to buy the pen.
[Q & A] The question is Kate wants to buy a special pen as a gift for her friend. The pen costs $30, and Kate only has money for a third of that amount. How much more money does she need to buy the pen?
The answer is 20

Step-by-step reasoning process: Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces.
[Q & A] The question is Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy. If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
The answer is 23

Step-by-step reasoning process: Each episode takes 20 * .5 = 10 minutes longer to film than it is. So it takes 20 + 10 = 30 minutes. They are filming 5 * 4 = 20 episodes. So it takes 20 * 30 = 600 minutes. This is equivalent to 600 / 60 = 10 hours.
[Q & A] The question is Tim host a show and they film multiple episodes per day. Each episode is 20 minutes long and it takes 50% longer than that to film each episode. Each week they show 5 episodes. How many hours would it take to film 4 weeks of episodes?
The answer is 10

Step-by-step reasoning process: James is 35 - 23 = 12 years younger than John. 5 years less than Tim's age is 79 - 5 = 74 years old. So John is 74 / 2 = 37 years old. That means James is 37 - 12 = 25 years old.
