Question: Wickham is throwing a huge Christmas party. He invites 30 people. Everyone attends the party, and half of the guests bring a plus one (one other person). He plans to serve a 3-course meal for the guests. If he uses a new plate for every course, how many plates does he need in total for his guests?
Answer: The number of guests that bring a plus one is 30 / 2 = 15 guests. The total number of guests at the party, including the plus ones, is 30 + 15 = 45 guests. Since there are 3 courses, Wickham will need 45 * 3 = 135 plates. The answer is 135.

Question: Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan's bird feeder feed weekly?
Answer: The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan's bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly. The answer is 21.

Question: Tony has to run several errands in a day. He needs to drive 10 miles to get groceries, 15 miles to get a haircut and 5 miles to go to a doctor's appointment. How many miles will Tony have driven when he is halfway through driving around for his errands?
Answer:
First, we need to find the total number of miles Tony will be driving by adding 10 + 15 + 5 = 30 miles in total. To determine the halfway point, we simply divide the total number of miles by 2, performing 30 / 2 = 15 miles driven when Tony is halfway done. The answer is 15.
