Several birds were sitting in the branches of a crape myrtle tree. There were three times more cardinals than bluebirds, but half as many swallows as bluebirds. If there were 2 swallows, what is the total number of birds in the crape myrtle tree?

With half as many swallows as bluebirds, there are 2*2=

<<2*2=4>>4 bluebirds. With three times more cardinals than bluebirds, there are 3*4=<<3*4=12>>12 cardinals, If there were 2 swallows, then the total number of birds in the crape myrtle tree is 2+4+12=<<2+4+12=18>>18 birds. #### 18 James visits 20 houses to try and make a sale. He manages to sell something in every house. The next day he visits twice as many houses but only sold to 80% of houses. If he sold two things at each house in each of the two days, how many items did he sell? The second day he visited 20*2=<<20*2=40>>40 houses So he sold things at 40*.8=<<40*.8=32>>32 houses So in total he sold things at 20+32=<<20+32=52>>52 houses That means he sold 52*2=<<52*2=104>>104 things #### 104 Angela's contribution is triple Brittany's contribution, and Brittany's contribution is triple Niraj's. If Niraj contributed $80, how much did everyone contribute in total? Brittany contributed 80*3 = <<80*3=240>>240 dollars. Angela contributed 240*3 = <<240*3=720>>720 dollars. Everyone contributed 80+240+720 = <<80+240+720=1040>>1040 dollars in total. #### 1040 Roberta wants to have a dinner party centered around soufflés. Each savory souffle calls for 8 eggs each and the dessert ones call for 6 eggs each. She wants to make 3 savory soufflés and 5 dessert soufflés for the party. How many eggs will she need? The savory soufflés need 8 eggs each and she wants to make 3 of these so she needs 8*3 = <<8*3=24>>24 eggs The dessert soufflés need 6 eggs each and she wants to make 5 of these so she needs 6*5 = <<6*5=30>>30 eggs For the dinner party she will need 24+30 = <<24+30=54>>54 eggs in total #### 54 Judson, Camilo, and Kenny decided to contribute money to paint their house. Judson contributed $500, Kenny contributed 20% more money than Judson, and Camilo contributed $200 more than Kenny. How much was the cost of painting the house? If Judson paid $500, Kenny contributed 20/100*$500 = $<<500*20/100=100>>100 more than Judson. In total, Kenny contributed $500+$100 = $<<500+100=600>>600 Kenny and Judson contributed a total of $600+$500 = $<<600+500=1100>>1100 If Camilo contributed $200 more than Kenny, then he contributed $600+$200 = $800 The total amount of money the three contributed for the house painting is $1100+$800 = $<<1100+800=1900>>1900 #### 1900 Lefty scores 20 points in a game and his teammate Righty scores half as many as Lefty does. Their other teammate scores 6 times as much as Righty does. What are the average points scored per player on the team? First, we need to determine how many points Righty scored. To do this we perform 20/2=<<20/2=10>>10 points since Righty scored half as many as Lefty did. Then, to find the other teammate's points we perform 10*6=<<10*6=60>>60 points scored, as they scored 6 times as many as Righty did. We then add all three teammates' points together, performing 20+10+60=<<20+10+60=90>>90 points as the first step towards finding the average. We then divide this sum by the total number of players we're averaging, getting 90/3=<<90/3=30>>30 points per player #### 30 48 children are trying to share a pack of sweets. After taking 4 sweets each, there is still a third of the original amount left. What is the original number of sweets in the pack? 48 children took 4 each for a total of 48*4 = <<48*4=192>>192 sweets If there is 1/3 left then 192 is 1-(1/3) = 2/3 of the original amount (The whole packet minus 1 third) Therefore 192 is 2/3 of the original amount: (2/3)* original amount = 192 Multiplying both sides of the equation by (3/2) gives: original amount = 192*(3/2) = <<192*3/2=288>>288 #### 288 In a survey about the student's favorite sports, 40% said they like basketball, 10% like chess, 28% like soccer, and the rest said they like badminton. If 250 students were interviewed, how many students identified chess or basketball as their favorite sport? The total percentage of students who said they like chess or basketball is 10% + 40% = 50%. So, 250 x 50/100 = <<250*50/100=125>>125 students like chess or basketball. #### 125 DJ Snake's friends decided to give him treats to celebrate his engagement. Moksi took him and his fiancee to a luxurious hotel for two nights at $4000 per night. Lil Jon bought them a car worth $30000, and Wynter presented them with a house worth four times the value of the car Lil Jon bought them. What was the total value of all the treats DJ Snake received on his engagement day? Moksi took DJ Snake and his fiancee to a luxurious hotel for two nights at $4000 per night, for a total of 2*$4000 = $<<2*4000=8000>>8000 If Lil Jon also bought them a car worth $30000, the value of the treats from Lil John and Moksi summed up to $8000+$30000 = $<<8000+30000=38000>>38000 Wynter presented them with a house worth four times the value of the car Lil Jon bought them, a total of 4*$30000 = $<<4*30000=120000>>120000 The total value of all the treats DJ Snake received on his engagement day is $120000+$38000 = $<<120000+38000=158000>>158000 #### 158000 Ms. Jones got thank you cards from 30% of her class. 1/3 of these contained a gift card for $10. If she got $50 in gift cards, how many students were in her class? She got 5 gift cards because 50 / 10 = <<50/10=5>>5 She got 15 thank you cards because 5 / (1/3) = <<5/(1/3)=15>>15 She has 50 students because 15 / .3 = <<15/.3=50>>50 #### 50
