Answer this question:3 cloves of garlic can repel 2 vampires, 8 vampire bats or 3 wights. How many cloves of garlic are needed to repel 30 vampires, 12 wights and 40 vampire bats?
First find the total number of cloves needed to repel the vampires: 30 vampires * 3 cloves / 2 vampires = 45 cloves. Then find the total number of cloves needed to repel the wights: 12 wights * 3 cloves / 3 wights = 12 cloves. Then find the total number of cloves needed to repel the vampire bats: 40 vampire bats * 3 cloves / 8 vampire bats = 15 cloves. Then add up these three amounts to find the total number of cloves needed: 45 cloves + 12 cloves + 15 cloves = 72 cloves.
The answer is 72.

Answer this question:Casey takes 6 hours to complete a marathon race, while Zendaya takes 1/3 times longer to cover the same distance. What is the average time the two take to complete to race?
Zendaya takes 1 / 3 * 6 hours = 2 hours longer to complete the marathon. To complete the marathon, Zendaya takes 6 hours + 2 hours = 8 hours. The combined time the two take to complete the marathon is 8 hours + 6 hours = 14 hours. The average number of hours Casey and Zendaya take to complete the marathon is 14 hours / 2 people = 7 hours / person.
The answer is 7.

Answer this question:Michael makes birdhouses to sell at craft shows. He charges $22 for each large birdhouse, $16 for each medium birdhouse, and $7 for each small birdhouse. This week, he sold 2 large birdhouses, 2 medium birdhouses, and 3 small birdhouses. How much money, in dollars, did he make this week?
Michael sold 2 large birdhouses for $22 each, so he made 2 * $22 = $44 from large birdhouse sales. Michael also sold 2 medium birdhouses for $16 each, so he made 2 * $16 = $32 from medium birdhouse sales. Michael sold 3 small birdhouses for $7 each, so he made 3 * 7 = $21 from small birdhouse sales. Since Michael made $44 from large birdhouse sales, $32 from medium birdhouse sales, and $21 for small birdhouse sales, he made $44 + $32 + $21 = $97 total this week.
The answer is 97.

Answer this question:The average of marks scored in four tests by Jake was 75. If jake scored 80 marks in the first test and 10 more in the second test, and an equal number of marks in the third and fourth test, calculate the marks he scored in the third test.
Since the average of marks scored in four tests by Jake was 75, the total marks that he scored in the four tests are 4 * 75 = 300. If jake scored 80 marks in the first test and 10 more in the second test, he scored 80 + 10 = 90 marks in the second test. The combined marks for the first and the second test is 90 + 80 = 170. The total marks Jake scored in the third and fourth test is 300 - 170 = 130. Since Jake scored an equal number of marks in the third and fourth tests, he scored 130 / 2 = 65 marks in each of the third and fourth tests.
The answer is 65.
