Nick is trying to raise money for a charity. He is selling candy bars for $5. He is also selling chocolate oranges for $10. He wants to raise $1000. He only had 20 chocolate oranges that he sold out. How many candy bars does Nick need to sell to reach his goal?
Nick has made 20 * $10 = $
<<20*10=200>>200 from the chocolate oranges. This means he needs to raise another $1000 - $200 = $<<1000-200=800>>800. He needs to sell a total of $800 / $5 = <<800/5=160>>160 candy bars to reach his goal. #### 160 Reese has been practicing piano for four hours every week. How many hours will he practice after five months? If Reese practices 4 four hours every week, in a month, with four weeks, he would have practiced for 4*4 = <<4*4=16>>16 hours. In five months, Reese would have practiced for 5*16 = <<5*16=80>>80 hours #### 80 Jenny got a 95 on her paper. Jason's grade was 25 points less than Jenny's, and Bob's grade was equal to half of Jason's grade. What was Bob's grade? First find Jason's grade by subtracting 25 from Jenny's grade: 95 - 25 = <<70=70>>70 Then divide Jason's grade by 2 to find Bob's grade: 70 / 2 = <<70/2=35>>35 #### 35 Matt has six cats and half of them are female. If each female cat has 7 kittens, and Matt sells 9 of them, what percentage of his remaining cats are kittens (rounded to the nearest percent)? First find the number of cats that are females: 6 cats / 2 = <<6/2=3>>3 cats Then find the total number of kittens born: 7 kittens/cat * 3 cats = <<7*3=21>>21 kittens Then subtract the 9 kittens that were sold: 21 kittens - 9 kittens = <<21-9=12>>12 kittens Then add the number of kittens to the number of adult cats to find the total number of cats: 12 kittens + 6 cats = <<12+6=18>>18 cats Then divide the number of kittens by the total number of cats and multiply by 100% to find the percentage of cats that are kittens: 12 kittens / 18 cats * 100% = 66.666...%, which rounds up to 67% #### 67 On a trip to visit the local museum, Mr. Gordon has taken 2/5 times more girls than boys. If their bus has a driver and an assistant, and the total number of boys on the trip is 50, calculate the total number of people on the bus considering the teacher also drives together with the students on the bus. The number of girls was 2/5 times more than the boys, which is 2/5*50 = <<2/5*50=20>>20 more girls. The total number of girls on the trip is 50+20 = <<50+20=70>>70 Together with the driver, the assistant driver, and the teacher, there were 70+50+3 = <<70+50+3=123>>123 people on the bus #### 123 Jane runs a small farm. She has 10 chickens that lay 6 eggs each per week. She can sell the eggs for $2/dozen. How much money will she make in 2 weeks if she sells all her eggs? Jane's chickens lay 10 chickens * 6 eggs = <<10*6=60>>60 eggs per week. Jane's chickens lay 60 eggs / 12 = <<60/12=5>>5 dozen eggs per week. Each week that Jane sells her eggs she can make 5 dozen * $2 = $<<5*2=10>>10 per week. In two weeks Jane would make 2 * $10/week = $<<2*10=20>>20. #### 20 Nate is reading a 400-page book. He finished reading 20% of the book. How many pages does he need to read to finish the book? Nate had read 400 x 20/100 = <<400*20/100=80>>80 pages. So, he still needs to read 400 - 80 = <<400-80=320>>320 pages to finish the book. #### 320 Jim reads at a rate of 40 pages an hour. He reads a total of 600 pages per week. He increases his reading speed to 150% of its former speed but reads 4 hours less per week. How many pages does he read a week now? He read 600/40=<<600/40=15>>15 hours per week So now he reads 15-4=<<15-4=11>>11 hours per week She now reads 40*1.5=<<40*1.5=60>>60 pages per hour So she reads 11*60=<<11*60=660>>660 pages per week #### 660 Juanita enters a drumming contest. It costs $10 to enter. She has 2 minutes to hit as many drums as she can. If she hits 200 drums, she can start to make money, equal to 2.5 cents for every drum hit. How many drums does she hit if she lost $7.5 for joining the contest? She made $2.5 from hitting drums because 10 - 7.5 = <<10-7.5=2.5>>2.5 She hit 200 drums to start making money She hit 100 drums in order to make the $2.5 because 2.5/.025 = 100 She hit 300 drums in total because 100 + 200 = <<100+200=300>>300 #### 300 Lizette scored 92 on her third quiz giving her an average of 94. What is Lizette's average in her first two quizzes? If Lizette's average on the 3 quizzes is 94, then the sum of her scores in the 3 quizzes is 94 x 3 = <<94*3=282>>282. This means that the sum of her scores in the first 2 quizzes is 282 - 92 = <<282-92=190>>190. Thus, her average for the first 2 quizzes is 190/2 = <<190/2=95>>95. #### 95
