Question: Jerry was contracted to work on a house by his neighbor Miss Stevie. The time it took him to fix the broken kitchen counter was three times longer than the time he took painting the house. He took 8 hours painting the house and then helped mow Miss Stevie's lawn, taking 6 hours. If he charged Miss Stevie $15 per hour of work, calculate the amount of money that Miss Stevie paid him.
Answer: Jerry took 2 * 8 = 24 hours fixing the broken kitchen counter. Together, painting the house and fixing the broken kitchen counter took him 24 + 8 = 32 hours. If he also took 6 hours mowing the lawn, the total time he spent working for Miss Stevie is 32 + 6 = 38. Since he charged $15 per hour of work, he was paid 38 * $15 = $570. The answer is 570.

Question: Lassie eats half of her bones on Saturday. On Sunday she received 10 more bones. She now has a total of 35 bones. How many bones did she start with before eating them on Saturday?
Answer: 35 bones at the end - 10 received = 25 on Sunday. Lassie ate half, so multiply by two to find the number of bones at the beginning which is 25 * 2 = 50 bones. The answer is 50.

Question: Roberto is out for a hike. He travels uphill at 2 MPH and downhill at 3MPH. The trail is 5 miles long. 60% is uphill and the rest is downhill. How long does it take him to complete it in minutes?
Answer: There is 3 miles uphill because 5 x .6 = 3. This takes him 1.5 hours because 3 / 2 = 1.5. This takes him 90 minutes because 1.5 x 60 = 90. 40% of the trail is downhill because 100 - 60 = 40. There are 2 miles of downhill because 5 x .4 = 2. This takes him 2 / 3 of an hour because 2 / 3 = (2 / 3). This takes him 40 minutes because 60 x (2 / 3) = 40. It takes him 130 minutes in total because 90 + 40 = 130. The answer is 130.

Question: It will cost $60 to rent a sailboat and $80 per hour to rent a ski boat. Ken rented a sailboat while Aldrich rented a ski boat. How much more did it cost Aldrich to rent the ski boat than Ken to rent a sailboat for three hours a day in two days?
Answer:
Ken paid $60 x 3 = $180 to rent a sailboat for 3 hours in a day. Aldrich paid $80 x 3 = $240 to rent a ski boat in 3 hours in a day. So Aldrich paid $240 - $180 = $60 more to rent a ski boat than Ken to rent the sailboat each day. Therefore, it cost Aldrich $60 x 2 = $120 more to rent a ski boat than Ken to rent the sailboat in two days. The answer is 120.
