In a Geometry exam, Madeline got 2 mistakes which are half as many mistakes as Leo. Brent scored 25 and has 1 more mistake than Leo. What is Madeline's score?

Leo got 2 x 2 =

<<2*2=4>>4 mistakes. So, Brent got 4 + 1 = <<4+1=5>>5 mistakes. This means that 25 + 5 = <<25+5=30>>30 is the perfect score. Hence, Madeline got a score of 30 - 2 = <<30-2=28>>28. #### 28 Addilynn went to the grocery store and bought six dozen eggs for use in her house. After two weeks, she used half of the eggs, then accidentally broke 15 of the remaining eggs while moving them to clean the shelves. How many eggs are left on the shelf? Since a dozen has 12 eggs, the total number of eggs that Addilynn bought is 6 dozen * 12 eggs/dozen = <<6*12=72>>72 eggs. If she used half of the eggs, the number of eggs left is 72 eggs / 2 = <<72/2=36>>36 eggs. While moving the eggs to clean the shelves, she broke 15 eggs, leaving 36 eggs - 15 eggs = <<36-15=21>>21 eggs. #### 21 Jason has six fish in his aquarium. He realizes that every day the number of fish doubles. On the third day he takes out one-third of the fish. On the fifth day he takes out one-fourth of the fish. On the seventh day he adds 15 more fish. How many fish in total does he have? Start by finding how many fish were in the aquarium on the third day 6 * 2 * 2 = <<6*2*2=24>>24. On day three, Jason took out one-third of the fish 24 / 3 = <<24/3=8>>8. So at the end of day three, he has 24 - 8 = <<24-8=16>>16 fish. On day five he has 16 * 2 * 2 = 64 fish, but he takes out one-fourth. So he took out 64 / 4 = <<64/4=16>>16 fishes. So at the end of day five, he has 64 - 16 = <<64-16=48>>48 fish. On day seven he has 48 * 2 * 2 = <<48*2*2=192>>192 fish. He adds in 15 more, so he has 192 + 15 = <<192+15=207>>207 fish in total. #### 207 There are 90 students who have lunch during period 5. Today, two-thirds of the students sat in the cafeteria, while the remainder sat at the covered picnic tables outside. But some yellow-jackets were attracted to their food, and so one-third of the students outside jumped up and ran inside to the cafeteria, while 3 of the students in the cafeteria went outside to see what all the fuss was about. How many students are now in the cafeteria? Originally, there were 90*2/3=<<90*2/3=60>>60 in the cafeteria. Originally, there were 90-60=<<90-60=30>>30 outside the cafeteria. Then 30*1/3=<<30*1/3=10>>10 ran inside The number of students inside the cafeteria grew by 10-3=<<10-3=7>>7. There are now 60+7=<<60+7=67>>67 students in the cafeteria. #### 67 Tom and Tim both brought 4, six-sided dice to school. How many total sides are there? There are 8 total dice because 4 plus 4 equals 8 There are 48 sides because 8 times six equals <<8*6=48>>48 #### 48 Giselle had 20 female doves in a birdhouse. After a month, the doves laid 3 eggs each. If 3/4 of the eggs hatched, calculate the total number of doves Giselle has now. If Giselle had 20 doves that laid 3 eggs each, the total number of eggs in the birdhouse is 20*3 = <<20*3=60>>60 eggs. If 3/4 of the eggs hatched into birds, their total number is 3/4*60 = <<3/4*60=45>>45 In the birdhouse, there are 20 initial doves + 45 new squabs = <<20+45=65>>65 birds #### 65 Tim is stuck in traffic for twice as long as he was driving. He drove 5 hours. How long was the trip? He was stuck in traffic for 5*2=<<5*2=10>>10 hours So his trip took 10+5=<<10+5=15>>15 hours #### 15 Oliver collects trading cards. He has twice as many Monster Club cards as Alien Baseball cards. His Battle Gremlins card collection is the largest at 48 cards, three times the size of his Alien Baseball card collection. How many Monster Club cards does Oliver have? Oliver’s Alien Baseball card collection has 48 / 3 = <<48/3=16>>16 cards. Oliver has twice as many Monster Club cards, so he has 16 * 2 = <<16*2=32>>32 Monster Club cards. #### 32 The kids in Ms. Swanson's class have an average of 5 zits each. The kids in Mr. Jones' class have an average of six zits each. If there are 25 kids in Ms. Swanson's class and 32 in Mr. Jones' class, how many more zits are there in Mr. Jones' class than in Ms. Swanson's? First find the total number of zits in Mr. Jones' class: 6 zits/kid * 32 kids = <<6*32=192>>192 zits Then find the total number of zits in Ms. Swanson's class: 5 zits/kid * 25 kids = <<5*25=125>>125 zits Then subtract the number of zits in Ms. Swanson's class from the number in Mr. Jones' class to find the difference: 192 zits - 125 zits = <<192-125=67>>67 zits #### 67 Malou got 91, 90, and 92 in her three quizzes. What is her average score? The sum of the three quizzes that Malou got is 91 + 90 + 92 = <<91+90+92=273>>273. So, her average score is 273/3 = <<273/3=91>>91. #### 91
