Q: Tim rides his bike back and forth to work for each of his 5 workdays. His work is 20 miles away. He also goes for a weekend bike ride of 200 miles.  If he can bike at 25 mph how much time does he spend biking a week?
A: He bikes 20 * 2 = 40 miles each day for work. So he bikes 40 * 5 = 200 miles for work. That means he bikes a total of 200 + 200 = 400 miles for work. So he bikes a total of 400 / 25 = 16 hours. The answer is 16.
Question: On each of 7 Mondays, it rained 1.5 centimeters. On each of 9 Tuesdays it rained 2.5 centimeters. How many more centimeters did it rain on Tuesdays than Mondays?
Answer: Mondays: 7 * 1.5 = 10.5. Tuesdays: 9 * 2.5 = 22.5. 22.5 - 10.5 = 12 cm. It rained 12 centimeters more on Tuesdays than on Mondays. The answer is 12.
[Question]Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell?
[Answer]A bag of feed is enough for 10 chickens because 20 / 2 = 10. Each chicken costs $.2 to raise because 2 / 10 = .2. Each chicken results in $1.3 of profit because 1.5 - .2 = 1.3. He sells 50 chickens because 65 / 1.3 = 50. The answer is 50.
Q: Kristy, a sales representative earns a basic salary of $7.50 per hour plus a 16% commission on everything she sells. This month, she worked for 160 hours and sold $25000 worth of items. Her monthly budget for food, clothing, rent, transportation, bills and savings is 95% of her total monthly earnings and the rest will be put towards insurance. How much did she allocate to insurance?
A: Kristy earns a basic salary of $7.50 x 160 = $1200. Her total commission is $25000 x 16 / 100 = $4000. Thus, her total earning is $1200 + $4000 = $5200. Her monthly budget aside from the insurance is $5200 x 95 / 100 = $4940. Therefore, she allocated $5200 - $4940 = $260 on insurance. The answer is 260.
