Juvy has a garden that has 20 rows with 10 plants in each row. She plants parsley in the first 3 rows and rosemary in the last two rows. The rest of the rows will be planted with chives. How many chives will Juvy plant?

How many rows did Juvy plant with parsley and rosemary? ** Juvy planted 3 + 2 =

<<3+2=5>>5 rows with parsley and rosemary. How many rows will be planted with chives? ** So, 20 - 5 = <<20-5=15>>15 rows will be planted with chives. How many chives will Juvy plant? ** Therefore, 15 x 10 = <<15*10=150>>150 chives will be planted. #### 150 Jeff has a shelter where he currently takes care of 20 cats. On Monday he found 2 kittens in a box and took them to the shelter. On Tuesday he found 1 more cat with a leg injury. On Wednesday 3 people adopted 2 cats each. How many cats does Jeff currently have in his shelter? How many cats did Jeff have before the kittens and injured cat? ** Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = <<20+2+1=23>>23 cats. How many cats did the 3 people take? ** 3 people took a total of 3 * 2 = <<3*2=6>>6 cats. How many cats does Jeff currently have in his shelter? ** After Wednesday, Jeff was left with 23 - 6 = <<23-6=17>>17 cats. #### 17 Miss Molly surveyed her class of 30 students about their favorite color. Half of the class answered green, one-third of the girls answered pink, and the rest of the class answered yellow. If there are 18 girls in the class, how many students like yellow best? How many students answered green? ** 30/2 = <<30/2=15>>15 students answered green. How many girls answered pink? ** 18/3 = <<18/3=6>>6 girls answered pink. How many students answered either green or pink? ** So, 15 + 6 = <<15+6=21>>21 students answered either green or pink. How many students answered yellow? ** Therefore, 30 - 21 = <<30-21=9>>9 answered yellow. #### 9 Carolyn is planning out her final essay. The introduction will be 450 words, the conclusion will be triple the length of the introduction, and each of the four body sections will be the same length. If her essay has to be 5000 words total, how long is each section? How many words are in the conclusion? ** First find the length of the conclusion by tripling the length of the introduction: 450 words * 3 = <<450*3=1350>>1350 words How many words are in the body sections? ** Then subtract the length of the introduction and conclusion from the total length to find the combined length of the body sections: 5000 words - 1350 words - 450 words = <<5000-1350-450=3200>>3200 words How many words are in each section? ** Then divide the combined length of the body section by the number of body sections to find the length of each section: 3200 words / 4 sections = <<3200/4=800>>800 words/section #### 800 Sophie buys five cupcakes at $2 each, six doughnuts at $1 each, four slices of apple pie at $2 per slice, and fifteen cookies at $0.60 each. How much does she spend in all? How much do the cupcakes cost? ** Five cupcakes cost 5 x $2 = $<<5*2=10>>10. How much do the doughnuts cost? ** Six doughnuts cost 6 x $1 = $<<6*1=6>>6. How much do the slices of apple pie cost? ** Four slices of apple pie cost 4 x $2 = $<<4*2=8>>8. How much do the cookies cost? ** And, fifteen cookies cost 15 x $0.60= $<<15*0.60=9>>9. How much does Sophie spend in all? ** Therefore, Sophie spends $10 + $6 + $8 + $ 9 = $<<10+6+8+9=33>>33. #### 33 Tod drives his family car 55 miles to the north and 95 miles to the west. If Tod constantly drives 25 miles an hour the entire trip how many hours did Tod drive? How many miles total did Tod drive? ** 55 miles north and 95 miles west give 55+95=<<55+95=150>>150 miles total How many hours did Tod drive? ** 150 miles at 25 miles an hour gives 150/25=<<150/25=6>>6 hours #### 6 Savannah is wrapping presents for her friends and family for Christmas. She has bought 3 rolls of wrapping paper to wrap 12 gifts. If it takes 1 roll to wrap 3 gifts and 1 roll to wrap 5 other gifts, if there is no wrapping paper leftover after Savannah wraps the rest of the gifts, how many gifts did she wrap with the third roll of paper? How many gifts did Savannah wrap with the first two rolls of paper? ** Savannah has 12 gifts to give her friends and family and has already wrapped 3 gifts + 5 gifts = 8 gifts already wrapped with the first two rolls of paper. How many gifts does Savannah wrap with the third roll of paper? ** She started off with 12 gifts to wrap and has already wrapped 8, 12 - 8 = <<12-8=4>>4 gifts she wraps with the third roll of paper. #### 4 Sedrach has 13 apple pies. If every apple pie can be quickly divided into halves and every half an apple pie can be split into 5 bite-size samples, how many people can taste Sedrach's apple pie if he divides them all into bite-size samples? How many bite sizes are in every apple pie? ** Every apple pie has 5 x 2 = <<5*2=10>>10 bite sizes How many people can taste Sedrach's apple pies? ** 13 x 10 = <<13*10=130>>130 people can taste Sedrach's apple pies #### 130 One student on a field trip counted 12 squirrels. Another counted a third more squirrels than the first student. How many squirrels did both students count combined? How many more squirrels did the second student count? ** The second student counted 12/3 = 4 more squirrels than the first student. How many squirrels did the second student count? ** The second student counted 12+4 = <<12+4=16>>16 squirrels. How many squirrels did both students count combined? ** Together, the first and second student counted 12+16 = <<12+16=28>>28 squirrels combined. #### 28 The teacher told the class that if they averaged at least 75% on their final exam, they could have a pizza party. Everyone took the exam on Monday, except for William, who was allowed to take it on Tuesday. If there are 30 people in the class, and the average before he took the test was a 74%, what score does he have to get to make sure they get to have a pizza party? Define a variable ** Let x be the score that William needs to achieve. How many people are there without William? ** Since there are 30 people in the class, there are 30 - 1 = <<30-1=29>>29 people without him. How many points does the class need to average? ** Since their average was a 74%, this means that (29 * 74 + x) / 30 >= 75. How many points does the class need to average? ** Thus, 29 * 74 + x >= 30 * 75 How many points does the class need to average? ** Thus, 29 * 74 + x >= 2250 How many points does the class need to average? ** Thus, 2146 + x >= 2250 How many points does William need to get? ** Thus, x >= 2250 - 2146 How many points does William need to get? ** Thus, x >= 94 #### 94
