Junior has 16 rabbits. On Monday, he bought 6 toys for his rabbits. On Wednesday, he bought twice as many toys as he did Monday. On Friday, he bought four times as many toys as he did on Monday, and on the next day he bought half as many toys as he did on Wednesday. If he split all the toys evenly between the rabbits, how many toys would each rabbit have?

On Wednesday, Junior bought 6*2 =

<<6*2=12>>12 toys. On Friday, Junior bought 6*4 = <<6*4=24>>24 toys. On Saturday he bought 12/2 = <<12/2=6>>6 toys. In total, Junior bought 6+12+24+6 = <<6+12+24+6=48>>48 toys. Each rabbit would have 48/16 = <<48/16=3>>3 toys. #### 3 Of the 24 students in class, one-third are in the after-school chess program, and half of those students will be absent from school on Friday for the regional chess tournament. How many of the students in this class are going to that tournament? There are 24/3=<<24/3=8>>8 students in the program. And 8/2=<<8/2=4>>4 go to the tournament. #### 4 John buys 2 dozen cookies. He eats 3. How many cookies does he have left? He got 2*12=<<2*12=24>>24 cookies So he has 24-3=<<24-3=21>>21 cookies left #### 21 Christina's age will be half of 80 years in five years to come. If Oscar will be 3/5 times as old as Christina is now in 15 years, calculate Oscar's age now. Christina's age will be half of 80 in five years to come, meaning in five years, Christina's age will be 1/2*80=40 years. If in five years Christina will be 40, currently she is 40-5=<<40-5=35>>35 years old. Oscar will be 3/5 times as old as Christina is now in 15 years, meaning he will be 3/5*35=<<3/5*35=21>>21 years old in 15 years. Currently, Oscar is 21-15=<<21-15=6>>6 years old. #### 6 A movie ticket for an adult costs $8, and a child's ticket costs $3. One adult is taking a group of children to the movies. She has $35. How many children can she take with her to the movies? Let X be the number of children the adult can take with her. She has $35, so she could buy one ticket for her and the rest for the children. So she has $35 - $8 = $<<35-8=27>>27 left for children. She could take $27 / $3/child = <<27/3=9>>9 children with her. #### 9 The basketball team is practicing their free-throws, making as many as they can in one minute. DeShawn made 12 free-throws, and Kayla made 50% more than DeShawn. If Annieka made 4 fewer than Kayla, how many did Annieka make? Kayla made 12*1.50=<<12*1.50=18>>18 free-throws. Annieka made 18-4=<<18-4=14>>14 free-throws. #### 14 A trolley driver picked up 10 people on his 1st stop. On the next stop, 3 people got off and twice as many people from the 1st stop got on. On the third stop, 18 people got off and 2 got on. How many people are currently on the trolley? Between the trolley driver and his first 10 customers, there are 1+10 = <<1+10=11>>11 people are currently on the trolley On his first stop, 10 people go on and twice as many people got on at the second stop so 10*2 = <<10*2=20>>20 people got on at the second stop. So at the second stop he had 11 people on board, 3 got off and 20 got on so he now has 11-3+20 = <<11-3+20=28>>28 people At his third stop 18 people got off and 2 got on so in total there are 28-18 +2 = <<28-18+2=12>>12 people on the trolley #### 12 Jimmy wants to play in the inflatable swimming pool in his backyard. The swimming pool is empty and the garage is locked, so he cannot use the hose to fill the pool. He finds a 2 gallon bucket and calculates that it takes 20 seconds to fill the bucket from the tap and carry it to the pool where he pours in the water. If the pool holds 84 gallons of water, how many minutes will it take Jimmy to fill the pool? It will take 84 / 2 = <<84/2=42>>42 trips to fill the pool with water. This will take Jimmy 42 trips * 20 seconds per trip = <<42*20=840>>840 seconds. This means that Jimmy will spend 840 seconds * 1 minute/ 60 seconds = 14 minutes filling the pool. #### 14 Sasha added 48 cards into a box. Her sister, Karen, then took out 1/6 of the cards Sasha added. If there are now 83 cards in the box, how many cards were originally in the box? Karen took out 48/6 = <<48/6=8>>8 cards from the box. Originally, the box had 83-40 = <<83-40=43>>43 cards. #### 43 Grayson drives a motorboat for 1 hour at 25 mph and then 0.5 hours for 20 mph. Rudy rows in his rowboat for 3 hours at 10 mph. How much farther, in miles, does Grayson go in his motorboat compared to Rudy? Grayson first travels 1 * 25 = <<1*25=25>>25 miles Then Grayson travels 0.5 * 20 = <<0.5*20=10>>10 miles Grayson travels a total of 25 + 10 = <<25+10=35>>35 miles Rudy travels 3 * 10 = <<3*10=30>>30 miles Grayson travels 35 - 30 = <<35-30=5>>5 miles more than Rudy #### 5
