[Question]A gift shop sells bracelets at $15 each, a gold heart necklace at $10, and a personalized coffee mug at $20. Raine buys three bracelets, two gold heart necklaces, and one coffee mug for her friends. How much change does Raine get back if she gives a one hundred dollar bill?
[Answer]Three bracelets cost 3 x $15 = $45. Two gold necklaces cost 2 x $10 = $20. Thus, the total amount is $45 + $20 + $20 = $85. Therefore, Raine gets a change of $100 - $85 = $15. The answer is 15.
Q: Conner has a dune buggy that he rides in the desert. On flat sand, it can ride at a speed of 60 miles per hour. When traveling on downhill slopes, it can race at 12 miles per hour faster than it can when it is on flat sand. And when riding on an uphill inclined slow, it travels at a speed 18 miles per hour slower than when it is riding on flat sand. If Conner rides his dune buggy one-third of the time on flat sand, one-third of the time on uphill slopes, and one-third of the time on downhill slopes, what is his average speed in miles per hour?
A: 12 mph faster than 60mph is 60 + 12 = 72 mph. 18 mph slower than 60 mph is 60 - 18 = 42 mph. If he spends 1 / 3 of the time at each of these three speeds, then he averages (60 + 72 + 42) / 3 = 58 mph. The answer is 58.
Question: Lexi wants to run a total of three and one-fourth miles. One lap on a particular outdoor track measures a quarter of a mile around. How many complete laps must she run?
Answer: There are 3 / 1 / 4 = 12 one - fourth miles in 3 miles. So, Lexi will have to run 12 (from 3 miles) + 1 (from 1 / 4 mile) = 13 complete laps. The answer is 13.
[Question]Grace is looking to plant some lettuce in her raised bed garden. Her raised bed is comprised of 2 large beds on top with 2 medium beds on the bottom. The top bed can hold 4 rows of lettuce with 25 seeds being sown per row. The medium bed can house 3 rows with 20 seeds being sown per row. How many seeds can Grace plant in all four beds of her raised bed garden?
[Answer]A large bed can hold 4 rows with 25 seeds per row, 4 * 25 = 100 seeds per large bed. 100 seeds per large bed and there are 2 beds, 100 * 2 = 200 seeds needed in total for both large beds. A medium bed can hold 3 rows with 20 seeds sown per row, 3 * 20 = 60 seeds per medium bed. 60 seeds per medium bed and there are 2 medium beds, 60 * 2 = 120 seeds needed in total for both medium beds. 200 seeds needed for the large beds combined with 120 seeds needed for the medium beds comes to 200 + 120 = 320 seeds needed to plant all four beds of the raised garden bed. The answer is 320.
Q: There are six chairs in each row in a church. If there are 20 rows of chairs in the church, and each chair holds five people, calculate the number of people who have to sit in the chairs for the church to be full.
A: If there are six chairs in each row in the church, the total number of chairs in the church is 6 * 20 = 120. Since each chair holds 5 people, 5 * 120 = 600 people must sit in all of the chairs for the church to be full. The answer is 600.
Question: Kameron has 100 kangaroos on his large farm; Bert has 20 kangaroos on his farm. In how many more days will Bert have the same number of kangaroos as Kameron does now if he buys kangaroos at the same rate of 2 new kangaroos per day?
Answer:
If Kameron has 100 kangaroos, he has 100 - 20 = 80 more kangaroos than Bert. Buying 2 kangaroos every day, it will take Bert 80 / 2 = 40 days to have the same number of kangaroos as Kameron has now. The answer is 40.
