[Question]A seminar is offered to a school for their teachers. The regular seminar fee is $150 but they offer a 5% discount if they register 2 days before the scheduled seminar. The school registered 10 teachers for the seminar a week before the schedule and it also released a $10 food allowance for each of the teachers. How much did the school spend in all?
[Answer]The school got a $150 x 5 / 100 = $7.50 seminar fee discount for each teacher. Each teacher's seminar fee costs $150 - $7.50 = $142.50. So, ten teachers' seminar fees cost $142.50 x 10 = $1425. The food allowance for 10 teachers amounts to $10 x 10 = $100. Therefore, the school spent a total of $1425 + $100 = $1525. The answer is 1525.
Q: Betty is growing parsnips in her vegetable garden. When the parsnips are grown, they are harvested and bundled into boxes that can hold up to 20 parsnips each. Each harvest, three-quarters of the boxes are full, and the remaining boxes are half-full. She gets an average of 20 boxes each harvest. How many parsnips does Betty grow in an average harvest?
A: If three - quarters of the boxes are full, then 1 – ¾ = ¼ of the boxes are half - full. On average, each harvest therefore has 20 boxes * 0.25 = 5 boxes that are half - full. This leaves 20 total boxes – 5 half - full boxes = 15 full boxes. Half - full boxes hold 20 parsnips / 2 = 10 parsnips each. In total, the half - full boxes, therefore, hold 5 boxes * 10 parsnips = 50 parsnips. The full boxes hold a total of 15 boxes * 20 parsnips = 300 parsnips. So Betty harvests a total of 50 + 300 = 350 parsnips in an average harvest. The answer is 350.
Question: Tom spends $250 to buy gems in a game he plays. The game gives 100 gems for each dollar you spend. Since he bought so many gems he got a 20% bonus of more gems. How many gems did he end up with?
Answer: He bought 250 * 100 = 25000 gems. He got a 25,000 * .2 = 5,000 gem bonus. So he got a total of 25000 + 5000 = 30,000 gems. The answer is 30000.
[Question]If Pam is currently twice as young as Rena is, and in 10 years Rena will be 5 years older than her, how old is Pam now?
[Answer]If Rena will be 5 years older than Pam in 10 years, this means they have a 5 year age gap. Therefore, to be twice Pam's age, Rena would have to be 5 * 2 = 10 years old. This means that Pam is currently 10 - 5 = 5 years old. The answer is 5.
Q: On the first day of the garden center sale, 14 marigolds were sold. The next day 25 more marigolds were sold. On the third day the center sold two times the number of marigolds it did on the day before. How many marigolds were sold during the sale?
A: When you add the first two days you get 14 + 25 = 39 marigolds. On the third day they sold 25 * 2 = 50 marigolds. During the three day sale 39 + 50 = 89 marigolds were sold. The answer is 89.
Question: A mother is making her own bubble mix out of dish soap and water for her two-year-old son. The recipe she is following calls for 3 tablespoons of soap for every 1 cup of water. If the container she hopes to store the bubble mix in can hold 40 ounces of liquid, and there are 8 ounces in a cup of water, how many tablespoons of soap should she add to the container (assuming that the soap itself doesn't count towards the capacity of the container)?
Answer:
The 40 - ounce container can hold 40 / 8 = 5 cups of water. This means that 5 * 3 = 15 tablespoons of soap should be used, since each cup of water requires 3 tablespoons of soap. The answer is 15.
