[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.
Q: At a roller derby, 4 teams are competing. Each team is made up of 10 members, and each member needs a pair of roller skates to compete in and another pair of skates as a backup. None of the skates have laces yet, so each member is offered 3 sets of laces per pair of skates. How many sets of laces have been handed out?
A: There are a total of 4 teams * 10 members per team = 40 team members. Each person receives 1 pair of competing roller skates + 1 pair of backup roller skates = 2 pairs of roller skates. So there are a total of 40 team members * 2 pairs of roller skates per team member = 80 roller skates. There were therefore 80 roller skates * 3 sets of laces per pair of roller skates = 240 sets of laces handed out. The answer is 240.
Question: Caroline has 40 pairs of socks. She loses 4 pairs of socks at the laundromat. Of the remaining pairs of socks, she donates two-thirds to the thrift store. Then she purchases 10 new pairs of socks, and she receives 3 new pairs of socks as a gift from her dad. How many pairs of socks does Caroline have in total?
Answer: After losing some socks, Caroline has 40 - 4 = 36 pairs of socks. Caroline donates 36 * (2 / 3) = 24 pairs of socks to the thrift store. After donating some socks, Caroline has 36 - 24 = 12 pairs of socks remaining. After getting new socks, Caroline has 12 + 10 + 3 = 25 pairs of socks. The answer is 25.
[Question]In a town where 60% of the citizens own a pet, half own a dog and 30 own a cat. How many citizens are in the town?
[Answer]Half the pet - owners have a cat because 1 - 1 / 2 = 1 / 2. There are 60 pet owners because 30 / (1 / 2) = 60. The town has 100 citizens because 60 / .6 = 100. The answer is 100.
Q: A couple's wedding reception had 180 people. The bride and groom had each invited 20 couples from their side of the family. The remaining guests were friends. How many friends attended the reception?
A: From the bride's side, 20 couples * 2 guests / couple = 40 guests attended. From the groom's side, 20 couples * 2 guests / couple = 40 guests attended. Therefore 180 guests - (40 guests + 40 guests) = 100 friends attended the reception. The answer is 100.
Question: A paper company decides to operate their business more sustainably. They decide that for every tree they chop down, they want to plant three more. If the company chops down 200 trees in the first half of the year and 300 more trees in the second half of the year, how many more trees does the company need to plant?
Answer:
The company has chopped down a total of 200 + 300 = 500 trees throughout the year. They plant 3 trees for every tree they chop so they need to plant 500 trees * 3 = 1500 trees. The answer is 1500.
