Hank gave his wife, Delphine, a box of 24 chocolates for Valentine's Day. On the first day, Delphine ate 4 chocolates. On the second day, she ate 3 less than twice as many chocolates as she ate the first day. On the third day, she ate two less than the number she ate on the first day. And on the fourth day, she ate one less than she ate the previous day. On the fifth day, how many chocolates remained uneaten?
Let's think: Twice as many chocolates as she ate the first day is 2 * 4 = 8 chocolates. And three less than twice as many chocolates as she ate the first day is 8 - 3 = 5 chocolates. Two less than the number she ate on the first day is 4 - 2 = 2 chocolates. One less than she ate the third day is 2 - 1 = 1 chocolate. By the end of the fourth day, 4 + 5 + 2 + 1 = 12 chocolates had been eaten. Thus, on the fifth day, 24 - 12 = 12 chocolates remained uneaten.. The answer is: 12.

It takes 15 minutes for Dante to go to Hidden Lake. From Hidden Lake, he has to walk back to the Park Office and it takes him 7 minutes. When he arrives there, he will have been gone from the Park Office 32 minutes altogether. If he had walked to the Lake Park restaurant from the Park office before taking the 15 minute walk to Hidden Lake, how long is the walk from Park Office to the Lake Park restaurant?
Let's think: If it takes 15 minutes for Dante to go to Hidden Lake and 7 minutes to walk back to the Park Office, he spends a total of 15 + 7 = 22 minutes on the trip. When Dante arrives at the Park Office, he will have been gone from the Park Office 32 minutes altogether, and since he passed by the Lake Park restaurant from The Park Office, his walk from Park Office to the Lake Park restaurant took 32 - 22 = 10 minutes.. The answer is: 10.

Five percent of the 300 senior students got a full merit college scholarship and ten percent of them got a half merit scholarship. How many senior students did not get any scholarships?
Let's think: 300 x 5 / 100 = 15 senior students got a full merit scholarship. 300 x 10 / 100 = 30 senior students got a half merit scholarship. So, a total of 15 + 30 = 45 students got scholarships. Therefore, 300 - 45 = 255 senior students did not get any scholarships.. The answer is: 255.

Penelope the pig eats 20 pounds of food per day, which is 10 times more than Greta the goose eats per day. Milton the mouse eats 1/100 as much as Greta the goose eats per day, but Elmer the elephant eats 4000 times more than Milton the mouse does per day. How much more, in pounds, does Elmer the elephant eat per day than Penelope the pig?
Let's think:
Greta the goose eats 20 / 10 = 2 pounds of food per day. Milton the mouse eats (1 / 100) * 2 = 1 / 50 of a pound of food per day. Elmer the elephant eats 4000 * (1 / 50) = 80 pounds of food per day. Thus, Elmer eats 80 - 20 = 60 pounds more food per day than does Penelope the pig.. The answer is: 60.
