Question: The buyers who came to Mr. Brandon's shop yesterday bought goods worth $80. If 2/5 of the total amount of sales Mr. Brandon made yesterday were credit sales, and the rest were cash sales, how much did Mr. Brandon get from cash sales?
Answer: 2 / 5 of the total amount of sales Mr. Brandon made yesterday, which were credit purchases, were worth 2 / 5 * $80 = $32. The cash sales that Mr. Brandon made yesterday was $80 - $32 = $48. The answer is 48.
[Question]Mark has two pets, a hare that runs 10 feet/second and a turtle that crawls 1 foot/second. If they're going to run a 20 foot-race, how much of a head start (in seconds) does the turtle need to finish in a tie?
[Answer]We can find how long the hare spends running by dividing the distance of the race by the hare's speed: 20 feet / 10 feet / second = 2 seconds. We can do the same for the turtle: 20 feet / 1 foot / second = 20 seconds. Finally, subtract the hare's run time from the turtle's run time to find the length of the head start the turtle needs: 20 seconds - 2 seconds = 18 seconds. The answer is 18.
Q: Shara collects shells. She had 20 shells before she went on vacation. On vacation, she found 5 shells per day for 3 days. Then he found 6 shells on the fourth day. How many shells does she have now?
A: Shara collected 5 x 3 = 15 shells for 3 days. So she collected 15 + 6 = 21 shells rom her vacation. Thus, she now has a total of 20 + 21 = 41 shells. The answer is 41.
Question: Michael has a lot of matchsticks at home and decides to use them to make miniature models. As he is about to start crafting, he has second thoughts and decides to only use half of his pile of matchsticks. He creates 30 matchsticks houses. If he has now used all of the matchsticks he intended to and each matchstick house uses 10 matchsticks, how many matchsticks did Michael have originally?
Answer: Michael has used a total of 30 matchstick houses * 10 matchsticks per matchstick house = 300 matchsticks. As he only used half of his collection for crafting, he must have originally had 300 matchsticks * 2 = 600 matchsticks. The answer is 600.
[Question]The age of Gladys is equal to twice the sum of the ages of Billy and Lucas. Billy is 3 times younger than Gladys who is 30 years old now. How old will Lucas be three years from now?
[Answer]Billy's age is 30 / 3 = 10 years old. The sum of the ages of Billy and Lucas is 30 / 2 = 15. So, Lucas is 15 - 10 = 5 years old now. Therefore, Lucas will be 5 + 3 = 8 years old three years from now. The answer is 8.
[Question]Iris has a berry farm. Her brother and sister help her to pick up the berries and sell them to the market. Iris picked 30 blueberries, her sister picked 20 cranberries, and her brother was able to pick 10 raspberries. If 1/3 of the total berries they were able to pick are rotten and the remaining 1/2 of the fresh berries need to be kept, how many berries will they be able to sell?
[Answer]
Iris and his brother and sister were able to pick a total of 30 + 20 + 10 = 60 berries. The rotten berries that needed to be thrown away are (1 / 3) x 60 = 20. So, the total number of fresh berries is 60 - 20 = 40. The berries they need to keep are (1 / 2) x 40 = 20. Therefore, the total number of berries they will be able to sell is 40 - 20 = 20. The answer is 20.
