There are twice as many cows as dogs at a petting farm. If there are currently 184 cows at the farm, and the farm owner decides to sell 1/4 of the cows and 3/4 of the dogs, how many animals are remaining on the farm?

If there are 184 cows, twice the number of dogs, then there are 184/2 =

<<184/2=92>>92 dogs on the farm. When the farm owner decided to sell 1/4 of cows, he sold 1/4*184 = 46 cows The total number of cows remaining on the farm is 184-46 = <<184-46=138>>138 If the farm owner also sold 3/4 of the dogs, he sold 3/4*92 = <<3/4*92=69>>69 The total number of dogs remaining on the farm is 92-69 = <<92-69=23>>23 The total number of animals remaining on the farm is 23+138 = <<23+138=161>>161 #### 161 Billy ate 20 apples this week. On Monday, he ate 2 apples. On Tuesday, he ate twice as many as he ate the day before. He’s not sure what he ate on Wednesday. On Thursday, he ate four times as many as he ate on Friday. On Friday, he ate half of the amount he ate on Monday. How many apples did he eat on Wednesday? On Tuesday, Billy ate 2 * 2 = <<2*2=4>>4 apples. On Friday, he ate 2 * 0.5 = <<2*0.5=1>>1 apple. On Thursday, he ate 4 * 1 = <<4*1=4>>4 apples. So for Monday, Tuesday, Thursday, and Friday, Billy ate a total of 2 + 4 + 4 + 1 = <<2+4+4+1=11>>11 apples. This means that on Wednesday, he must have eaten 20 – 11 = <<20-11=9>>9 apples. #### 9 Biff and Kenneth decide to compete in a 500-yard rowboat race. If Biff rows at a speed of 50 yards per minute and Kenneth rows at a speed of 51 yards per minute, how many yards past the finish line will Kenneth be when Biff crosses the finish line? Traveling at 50 yards per minute, Biff can travel 500 yards in 500/50=<<500/50=10>>10 minutes. In 10 minutes, traveling at 51 yards per minute, Kenneth can travel 10*51=<<10*51=510>>510 yards. Thus, Kenneth will be 510-500=<<510-500=10>>10 yards past the finish line when Biff crosses the finish line. #### 10 Joe found a new series to watch with a final season that will premiere in 10 days. The series has 4 full seasons already aired; each season has 15 episodes. To catch up with the season premiere he has to watch all episodes. How many episodes per day does Joe have to watch? The total number of episodes is 4 seasons x 15 episodes/season = <<4*15=60>>60 episodes Joe has to watch per day 60 episodes ÷ 10 days= <<60/10=6>>6 episodes/day #### 6 In a classroom, there are blue chairs, green chairs, and white chairs. There are 10 blue chairs. The green chairs are 3 times as many as the blue chairs, and there are 13 fewer white chairs than the green and blue chairs combined. How many chairs are there in a classroom? There are 10 x 3 = <<10*3=30>>30 green chairs. The total number of blue and green chairs is 10 + 30 = <<10+30=40>>40. So, there are 40 - 13 = <<40-13=27>>27 white chairs. Therefore, there are 40 +27 = <<40+27=67>>67 chairs in a classroom. #### 67 Every day Tom drinks 5 12-oz cans of soda plus 64 ounces of water. How many ounces of fluid does he drink a week? He drinks 12 * 5 = <<12*5=60>>60 ounces of soda a day So he drinks 60 + 64 = <<60+64=124>>124 ounces of liquid a day So in total he drinks 124 * 7 = <<124*7=868>>868 ounces of liquid a week #### 868 A banana plantation on Jakies Island can produce ten times as many bananas as a banana plantation on a nearby island. If the banana plantation on the nearby island produced 9000 bananas in a year, what's the total banana produce from the two islands that year? Jakies island produced ten times as many bananas as the nearby island, a total of 10*9000 = <<10*9000=90000>>90000 bananas. Together, the two islands produced 90000+9000= <<90000+9000=99000>>99000 bananas in that year. #### 99000 Cristian has 50 more black cookies in his cookie jar than white cookies. He eats half of the black cookies and 3/4 of the white cookies. If he initially had 80 white cookies, how many cookies are remaining within the cookie jar altogether? Cristian eats 3/4*80 = <<3/4*80=60>>60 white cookies from the jar, 3/4 of the total number of white cookies in the cookie jar. The number of white cookies remaining in the cookie jar is 80-60 =<<80-60=20>>20 In his cookie jar, Cristian also has 80+50 = <<80+50=130>>130 black cookies. He eats 1/2*130 = <<130*1/2=65>>65 black cookies from the cookie jar. He remains with 130-65 = <<130-65=65>>65 black cookies after eating half of them. In total, Cristian has 65+20 = <<65+20=85>>85 cookies remaining in the jar. #### 85 There are 2000 pinecones on the ground. 20% are eaten by reindeer. Twice as many are eaten by squirrels as reindeer. 25% of the remainder are collected to make fires. How many pinecones are left? First find the number of pinecones eaten by reindeer: 20% * 2000 pinecones = <<20*.01*2000=400>>400 pine cones Then find the total number of pinecones eaten by squirrels: 400 pine cones * 2 = <<400*2=800>>800 pine cones Then subtract those two amounts to find the number of pinecones left: 2000 pinecones - 400 pine cones - 800 pine cones = <<2000-400-800=800>>800 pinecones Divide that number by 4 to find the number that are collected for fires: 800 pinecones / 4 = <<800/4=200>>200 pine cones Then subtract that number from the 800 pinecones to find the total left on the ground: 800 pine cones - 200 pinecones = <<800-200=600>>600 pine cones #### 600 On a highway, the total number of vehicles passing is 300. If the number of cars on the highway is twice the number of trucks, find out the total number of trucks on the highway? If we assume that the number of trucks on the highway is t, the number of cars on the highway will be 2*t = 2t The total number of cars and trucks on the road is 2t+t= 300 The number of vehicles on the road is 3t=300 The are t=300/3 trucks on the highway. This means there are t=<<100=100>>100 trucks on the road. #### 100
