Question: If 100 pieces, each 15 centimeters long, are cut from a 51-meter long ribbon, how much ribbon remains ?
Answer: The total length cut from the 51 - meter ribbon is 100 x 15 centimeters = 1500 centimeters. Since 1 meter is equal to 100 centimeters, then 1500 centimeters is equal to 1500 / 100 = 15 meters. Therefore, 51 - 15 = 36 meters of ribbon remains. The answer is 36.
[Question]A mother is serving pizza at her son's birthday party. After buying 5 pizzas, she must decide how many slices to divide each pizza into so that everyone at the party ends up with an equal number of slices. There are a total of 20 children at the party, and she can choose to divide each pizza into either 6, 8, or 10 slices. Assuming she does not want to throw away any pizza, how should many slices should she choose to divide the pizzas into to make sure everyone receives an equal amount?
[Answer]Checking each possibility, we can see that dividing each pizza into 6 slices yields 5 * 6 = 30 total slices, dividing each pizza into 8 slices yields 5 * 8 = 40 total slices, and dividing each pizza into 10 slices yields 5 * 10 = 50 total slices. Because each child must receive the same number of slices, the total number of slices must be evenly divisible by 20. The only option that satisfies this requirement is dividing the pizza into 8 slices, as 40 / 20 = 2 slices per child. Therefore, the mother should divide each pizza into 8 slices. The answer is 8.
Q: Barry goes to a shop to buy a shirt he'd been admiring for quite some time. He tells the attendant that it's his birthday so she decides to give him a 15% special discount. The price tag on the shirt says $80. How much is he supposed to pay now, considering the special discount?
A: 15% of $80 = (15 / 100) * $80 = $12. The dollar amount of the discount is $12 so he is supposed to pay just $80 - $12 = $68. The answer is 68.
Question: On a four-day trip, Carrie drove 135 miles the first day, 124 miles more the second day, 159 miles the third day, and 189 miles the fourth day. If she had to charge her phone every 106 miles, how many times did she charge her phone for the whole trip?
Answer: Carrie drove 135 + 124 = 259 miles on the second day. Carrie drove 135 + 259 + 159 + 189 = 742 miles for the whole trip. Carries charged her phone 742 / 106 = 7 times. The answer is 7.
[Question]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?
[Answer]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.
