A: Catriona has 8 + 4 = 12 angelfish. She also has 12 x 2 = 24 guppies. Thus, she has 8 + 12 + 24 = 44 fish in her aquarium. The answer is 44.
Question: Adam's wardrobe is too crowded so he decides to donate some of his clothes to a charity shop. He takes out 4 pairs of pants, 4 jumpers, 4 pajama sets (top and bottom), and 20 t-shirts, then asks his friends if they have anything they want to donate. 3 of his friends donate the same amount of clothing as Adam each. Then he takes another look over his clothing and decides that he actually wants to keep half of his clothes. How many articles of clothing are being donated in total?
Answer: As pajama sets are made up of a top and a bottom, there are 4 pajama sets * 2 = 8 articles of clothing from Adam's donation. In total, Adam is donating 4 pairs of pants + 4 jumpers + 8 pajama pieces + 20 t - shirts = 36 articles of clothing. Together, the 3 friends donate a total of 36 articles of clothing per friend * 3 friends = 108 articles of clothing. Adam changes his mind and takes back half, which means he is now actually donating 36 / 2 = 18 articles of clothing. There is therefore now a total of 108 + 18 = 126 articles of clothing being donated. The answer is 126.
[Question]Emily just purchased 2 pairs of curtains for $30.00 each and 9 wall prints at $15.00 each. The store also offers an installation service. For $50.00 they will come to your house and professionally hang your curtains and prints. If Emily agrees to this service, how much will her entire order cost?
