Anne is drawing pictures. She has 12 markers and she notices that each one lasts for about 1.5 drawings. If she has already made 8 drawings, how many more can she make before she runs out of markers?
She can make 18 drawings in total because 12 x 1.5 =
<<12*1.5=18>>18 She can make ten more because 18 - 8 = <<18-8=10>>10 #### 10 Aubree saw 20 beavers and 40 chipmunks by a tree when going to school and scared them away when they saw her. While coming back from school, she realized the number of beavers had doubled and the number of chipmunks had decreased by 10. What's the total number of animals she saw that day? When going to school, she saw 40+20 = <<40+20=60>>60 animals. The number of beavers doubled to 20*2 = <<20*2=40>>40 beavers The number of chipmunks decreased to 40-10 = <<40-10=30>>30 chipmunks. The total number of animals she saw on that day is 30+40+60 = <<30+40+60=130>>130 animals #### 130 Hannah ran 9 kilometers on Monday. She ran 4816 meters on Wednesday and 2095 meters on Friday. How many meters farther did she run on Monday than Wednesday and Friday combined? Wednesday + Friday = 4816 + 2095 = <<4816+2095=6911>>6911 meters 9 km = <<9*1000=9000>>9000 meters 9000 - 6911 = <<9000-6911=2089>>2089 meters Hannah ran 2089 meters farther on Monday than Wednesday and Friday. #### 2089 Daniel buys a magazine costing $0.85 and a pencil costing $0.50. He pays with a coupon that gives him $0.35 off. How much does he spend? Daniel buys both magazine and pencil for $0.85 + $0.50 = $<<0.85+0.5=1.35>>1.35. The coupon gives him a total cost of $1.35 - $0.35 = $<<1.35-0.35=1>>1. #### 1 Ziggy is a club DJ. Typically, Ziggy gets 30 song requests every night. Half the songs requested are electropop. A third of that amount are requests for dance music. Five song requests are rock music, and song requests for oldies are three less in number than rock requests. Ziggy plays a DJ’s choice song half the number of times he plays an oldie. Ziggy also sometimes gets rap song requests. Typically, how many rap songs does Ziggy get requested every night? Ziggy gets 30 / 2 = <<30/2=15>>15 electropop song requests every night. There are 15 / 3 = <<15/3=5>>5 dance song requests every night. There are 5 - 3 = <<5-3=2>>2 oldies requests every night. Ziggy plays DJ’s choice 2 / 2 = <<2/2=1>>1 time every night. Thus, Ziggy gets 30 - 15 - 5 - 5 - 2 - 1 = <<30-15-5-5-2-1=2>>2 rap songs requested every night. #### 2 Youngsville had a population of 684 people. The town had a growth spurt and the population increased by 25% then they witnessed that 40% of the population moved away. What is the current population? The town had 684 people then had a 25% growth spurt increasing the population by 684*.25 = 171 people The town had 684 people then they added 171 people bringing the population to 684+171 = <<684+171=855>>855 people There were 855 people and 40% moved away so it decreased by 855*.40 = 342 The population was 855 and 342 people moved away making the new population 855-342 = <<855-342=513>>513 people #### 513 Dylan filled his glass with ice cubes before he poured his soda into it. He counted and there were 8 ice cubes in his glass. Later when he prepares a pitcher of lemonade he puts two times as many ice cubes in the pitcher. Then it is time to refill the ice cube trays which have 12 spaces each for ice cubes. How many trays does Dylan need to fill if he used exactly all the ice they had in them? Dylan uses 8 ice cubes in his glass plus 2 x as many for the pitcher of lemonade, 8 x 2 = 16 ice cubes. Those 16 ice cubes + the 8 before means that the ice cube trays originally held 16 + 8 ice cubes = <<16+8=24>>24 ice cubes. Each ice cube tray holds 12 ice cubes, 24 ice cubes / 12 spaces in the trays = <<24/12=2>>2 total ice cube trays. #### 2 It takes Emmalyn and her research team, the Polar Bears, 30 minutes to fully navigate around a volcanic island. On Saturday, they decided to start off by rounding the island once. They then re-grouped and planned out the rest of their weekend research schedule. They completed 10 more round that day and then went home. When they came on Sunday, they were able to complete 15 rounds. Calculate the total time, in minutes, the Polar Bears spent circling the island over that weekend. On the first day, they started off doing one round of 30 minutes. The team did ten more rounds on day one which took 10*30 = <<10*30=300>>300 minutes. The total time they took circumnavigating the land on the first day is 300+30 = <<300+30=330>>330 minutes. On the second day, they did 15 rounds, which took 30 minutes each, giving 15*30 = <<15*30=450>>450 minutes. The total number of rounds took 330+450 = <<330+450=780>>780 minutes. #### 780 Lilly and Fiona are cleaning a room. Between them, it takes 8 hours to clean the room. A quarter of the time spent cleaning was by Lilly and Fiona was responsible for the rest of the cleaning. How long, in minutes, was Fiona cleaning? Lilly cleaned for 8 hours / 4 = <<8/4=2>>2 hours. This means that Fiona was cleaning for 8 hours total cleaning – 2 hours Lilly’s cleaning = <<8-2=6>>6 hours. So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = <<6*60=360>>360 minutes. #### 360 Daryl is loading crates at a warehouse and wants to make sure that they are not overloaded. Each crate can weigh up to 20kg and he has 15 crates he can fill. He has 4 bags of nails to load, each of which weighs 5kg; he has 12 bags of hammers, each of which weighs 5 kg; he also has 10 bags of wooden planks, each of which weighs 30kg and can be sub-divided. He realizes that he has too much to load and will have to leave some items out of the crates to meet the weight limit. In kg, how much is Daryl going to have to leave out of the crates? Daryl can load up to 15 crates * 20kg per crate = <<15*20=300>>300kg. The nails weigh a total of 4 bags of nails * 5kg per bag of nails = <<4*5=20>>20kg. The hammers weigh a total of 12 bags of hammers * 5kg per bag of hammers = <<12*5=60>>60kg. The wooden planks weigh a total of 10 bags of wooden planks * 30kg per bag of wooden planks= <<10*30=300>>300kg. So in total, Daryl’s items weigh a total of 20kg nails + 60kg hammers + 300kg wooden planks = <<20+60+300=380>>380kg. He will therefore need to leave out 380kg in items – 300kg weight limit = <<380-300=80>>80kg. #### 80
