[Question]The length of a red bus is four times the length of an orange car. The length of the orange car is also 3.5 times shorter than the length of a yellow bus. If the yellow bus and red bus are sitting next to each other, what length of the red bus may the yellow bus driver see if the red bus is 48 feet long?
[Answer]If the red bus is 48 feet long, the orange car is 48 / 4 = 12 feet long. Since the length of the orange car is 3.5 times shorter than a yellow bus, the yellow bus is 3.5 * 12 = 42 feet long. If sitting next to each other, the driver of the yellow car will see 48 - 42 = 6 feet of the red bus. The answer is 6.
Q: Janice bought five juices for $10 in total and two sandwiches for $6 in total. How much would she need to pay, if she would only buy one sandwich and one juice?
A: Janice bought five juices for $10, so one juice costs 10 / 5 = $2. She also bought two sandwiches for $6, so one sandwich costs 6 / 2 = $3. So for one juice and one sandwich, Janice would need to pay 2 + 3 = $5. The answer is 5.
Question: A school is adding 5 rows of seats to the auditorium. Each row has 8 seats and each seat costs $30. A parent, being a seat manufacturer, offered a 10% discount on each group of 10 seats purchased. How much will the school pay for the new seats?
Answer: Ten seats amount to $30 x 10 = $300. So there is $300 x 10 / 100 = $30 discount for each 10 seats purchased. Thus, the total cost for every 10 seats is $300 - $30 = $270. The school is going to buy 5 x 8 = 40 seats. This means that the school is going to buy 40 / 10 = 4 sets of 10 seats. Therefore, the school will pay a total of $270 x 4 = $1080 for the new seats. The answer is 1080.
