John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?

He now buys 4/2=

<<4/2=2>>2 coffees The new price is 2*.5=$<<2*.5=1>>1 more than the old price So he now pays 2+1=$<<2+1=3>>3 per coffee So he spends 3*2=$<<3*2=6>>6 He used to spend 4*2=$<<4*2=8>>8 So he saves 8-6=$<<8-6=2>>2 per day #### 2 There are 3414 yellow balloons and there are 1762 more black balloons than yellow balloons. If the balloons will be evenly divided among 10 schools, how many balloons will one school receive? Black balloons: 3414 + 1762 = <<3414+1762=5176>>5176 Total balloons: 3414 + 5176 = <<3414+5176=8590>>8590 8590/10 = <<8590/10=859>>859 Each school will receive 859 balloons. #### 859 Betty has 20 books, and her sister has 1/4 times more books than Betty. What's the total number of books the two have? Betty's sister has 1/4 * 20 books = <<1/4*20=5>>5 more books. The total number of books Betty's sister has is 20 books + 5 books = <<20+5=25>>25 books The total number of books the two have is 25 books + 20 books = <<25+20=45>>45 books #### 45 Yun had 20 paperclips initially, but then lost 12. Marion has 1/4 more than what Yun currently has, plus 7. How many paperclips does Marion have? Yun has 20-12= <<20-12=8>>8 paperclips. Marion has 8/4 + 7 = <<8/4+7=9>>9 paperclips #### 9 To eat to when she gets full, Michaela needs 20 oranges. Cassandra needs twice as many oranges as Michaela to eat until she gets full. If they picked 90 oranges from the farm today, how many oranges would remain after they've both eaten until they were full? Since Michaela needs 20 oranges to eat to her full, and Cassandra eats twice as much to have her full, Cassandra needs 2*20 = <<20*2=40>>40 oranges to eat. They eat 20+40 = <<20+40=60>>60 oranges together to have their fill. If they picked 90 oranges today, after eating 60 together, 90-60 = <<90-60=30>>30 oranges would remain. #### 30 With 40 seconds left to play in the basketball game, the Dunkinville Hornets were leading the Fredingo Fireflies by a score of 86 to 74. In the remaining seconds in the game, the Fireflies scored 7 three-point baskets while holding the Hornets to only 2 two-point baskets to win the game. How many more points did the Fireflies score in the game than did the Hornets? In the final 40 seconds, the Fireflies scored seven 3-point baskets to improve their score by 3*7=<<7*3=21>>21 points. Thus, the Fireflies final total was 74+21=<<74+21=95>>95 points. In the final 40 seconds, the hornets scored an additional two 2-point baskets to improve their score by 2*2=<<2*2=4>>4 points. Thus, the Hornets final total was 86+4=<<86+4=90>>90 points. The final difference in points between the two teams was 95-90=<<95-90=5>>5 points. #### 5 Nina loves to travel. She tries to travel at least 400 kilometers in one month outside of her home country. Every second month she does twice that distance. If she were able to keep up with her resolution, how many kilometers would she travel during 2 years? Every second month Nina does twice the regular distance, which means 400 * 2 = <<400*2=800>>800 kilometers. Two years is 24 months, so half of this time is 24 * 0.5 = <<24*0.5=12>>12 months. So in 12 months Nina does 400 * 12 = <<400*12=4800>>4800 kilometers. And in the other 12 months, she does 800 * 12 = <<800*12=9600>>9600 kilometers. So in two years, Nina would be able to make 4800 + 9600 = <<4800+9600=14400>>14400 kilometers. #### 14400 Jaynie wants to make leis for the graduation party. It will take 2 and half dozen plumeria flowers to make 1 lei. If she wants to make 4 leis, how many plumeria flowers must she pick from the trees in her yard? To make 1 lei, Jaynie will need 2.5 x 12 = <<12*2.5=30>>30 plumeria flowers. To make 4 leis, she will need to pick 30 x 4 = <<30*4=120>>120 plumeria flowers from the trees. #### 120 The Great Pyramid of Giza was the tallest man-made structure on earth for almost 4000 years. It is 20 feet taller than 500 feet, and 234 feet wider than it is tall. What is the sum of the height and width of the Great Pyramid of Giza in feet? The height is 20 feet taller than 500 feet, or 500+20=<<20+500=520>>520 feet. The structure is 234 feet wider than it is tall, or a width of 520+234=754 feet wide. Therefore, the sum of the height and width of the Great Pyramid of Giza is 520+754=<<520+754=1274>>1274 feet. #### 1274 Natalie has $26 to go shopping. She bought a jumper for $9, a T-shirt for $4, and a pair of heels for $5. How much money does Natalie have left? The total cost of the clothes is $9 + $4 + $5 = $<<9+4+5=18>>18. Natalie has $26 − $18 = $8 left. #### 8
