Question: Jean needs to buy 10 new pairs of pants. A store is running a sale for 20% off. If the pants normally retail for $45 each how much will she need to pay for all of them after paying a 10% tax?
Answer: The discount is 45 * .2 = $9 off each pair. So she pays 45 - 9 = $36 each. So it will cost 36 * 10 = $360 before tax. The tax will add 360 * .1 = $36. So she has to pay 360 + 36 = $396. The answer is 396.
[Question]Anne drops a mirror and breaks it into 60 pieces. She sweeps up half of them, then her cat steals 3 pieces and her boyfriend picks up 1/3 of the remaining pieces. How many pieces does her boyfriend pick up?
[Answer]First find the number of pieces left after Anne sweeps up: 60 pieces / 2 = 30 pieces. Then subtract the number her cat takes: 30 pieces - 3 pieces = 27 pieces. Divide that number by 3 to find how many pieces her boyfriend picks up: 27 pieces / 3 = 9 pieces. The answer is 9.
Q: There are 20 dolphins in the aqua park. One-fourth of the dolphins are fully trained. Two-third of the remaining dolphins are currently in training and the rest will be trained next month. How many dolphins will be trained next month?
A: 20 x 1 / 4 = 5 dolphins are fully trained. So, 20 - 5 = 15 dolphins are not yet fully trained. 15 x 2 / 3 = 10 are currently in training. Therefore, 15 - 10 = 5 dolphins will be trained next month. The answer is 5.
Question: Sherman has a 30-minute commute to the office and a 30-minute commute home every day. On the weekends, he spends 2 hours, each day, driving his kids to their different activities. How many hours does Sherman drive a week?
Answer: He drives 30 minutes to work and 30 minutes home every day for a total of 30 + 30 = 60 minutes. He makes this drive 5 days a week for a total of 5 * 60 = 300 minutes. There are 60 minutes in 1 hour and he drives 300 minutes, 5 days a week so that's 300 / 60 = 5 hours. He drives 2 hours on both Saturday and Sunday so he drives 2 * 2 = 4 hours on the weekends. He commutes 5 hours during the week and spends 4 hours driving on the weekend for a total of 5 + 4 = 9 hours. The answer is 9.
Q: Every year 20 ducks from a flock are killed but another 30 are born. The original flock size is 100 ducks. After 5 years they join with another flock of 150 ducks. How many ducks are in the combined flock?
A:
The original flock gains 30 - 20 = 10 ducks per year. So after 5 years they have gained 10 * 5 = 50 ducks. So the original flock has 100 + 50 = 150 ducks. So the combined flock has 150 + 150 = 300 ducks. The answer is 300.
