Q: Stoney Hollow Middle School is taking a field trip to the zoo. There are 109 fifth graders, 115 sixth graders, and 118 seventh graders. There are 4 teachers and 2 parents from each grade coming along to chaperone on the trip. There are 72 seats on each school bus. How many buses are needed for the field trip?
A: There are 109 fifth graders + 115 sixth graders + 118 seventh graders = 342 students going on the trip. There are 4 teachers + 2 parents = 6 adults going on the field trip for each grade. There are 3 grades going, so 3 grades x 6 adults / grade = 18 total adults going on the trip. There are 342 students + 18 adults = 360 people going on the trip. So, 360 people / 72 seats = 5 buses. The answer is 5.

Q: Andrea buys herself a pony for her 30th birthday. She pays $500/month to rent a pasture for it, $10 a day for food, and $60/lesson for two lessons a week. How much does she spend on her pony in a year?
A: First find the annual cost of food: $10 / day * 365 days = $3650. Then find how much she spends a week on lessons: $60 / lesson * 2 lessons = $120. Then multiply that weekly cost by the number of weeks per year to find the annual cost: $120 / week * 52 weeks / year = $6240. Then find the annual cost of the pasture: $500 / month * 12 months / year = $6000. Then add all the costs to find the total cost: $6000 + $6240 + $3650 = $15890. The answer is 15890.

Let X be the number of years before Fouad's age doubles Ahmed's age. So (X + 11) * 2 = X + 26. So X * 2 + 22 = X + 26. So X = 26 - 22 = 4 years. The answer is 4.
