Kelly, Brittany, and Buffy went swimming at Salt Rock Lake and held a contest to see who could hold their breath underwater for the longest amount of time. Kelly held her breath underwater for 3 minutes. Brittany held her breath underwater for 20 seconds less time than than Kelly did, and Buffy held her breath underwater for 40 seconds less time than Brittany did. How long, in seconds, did Buffy hold her breath underwater?
Let's think: Kelly held her breath for 3 minutes, or 3 * 60 = 180 seconds. Brittany held her breath for 20 seconds less time than Kelly did, or 180 - 20 = 160 seconds. And Buffy held her breath for 40 seconds less time than Brittany did, or for 160 - 40 = 120 seconds.. The answer is: 120.

Leticia, Nina, and Rosalie have a total of 25 people on their dance team. If 8 people quit, but 13 new people got in, how many people are there now on the team?
Let's think: There are 25 - 8 = 17 people in their dance team after 8 people quit. Therefore, there are 17 + 13 = 30 people now after 13 new people got in.. The answer is: 30.

Every year, four clowns and thirty children go on a carousel. This year, the candy seller, at the carousel, had 700 candies. The candy seller then sold 20 candies, to each of the clowns and the children, who attended. How many candies did he have left?
Let's think: Since there are four clowns at the carousel this year, the candy seller sold 20 * 4 = 80 candies to all the clowns. The thirty children also bought 20 * 30 = 600 candies in total. Altogether, the candy seller sold 600 + 80 = 680 candies to the clowns and children at the carousel. The number of candies the candy seller has left is 700 - 680 = 20.. The answer is: 20.

An old pirate wants to leave his treasure on an island. He has 3500 gold coins. He wants to spread this equally across 5 chests. Additionally, he will put a total of 500 silver coins and twice as many bronze coins as silver, all distributed equally across the chests. How many coins in total will be in each chest?
Let's think:
There will be 3500 gold coins / 5 chest = 700 gold coins in every chest. So, there will be 500 silver coins / 5 chests = 100 silver coins in each chest. Then, the number of bronze coins is double the number of silver coins, so there are 2 * 500 = 1000 bronze coins. So there will be 1000 bronze coins / 5 chests = 200 bronze coins in each chest. Finally, the total number of coins in every chest will be 700 gold coins + 100 silver coins + 200 bronze coins = 1000 coins.. The answer is: 1000.
