Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?

If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows.

Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 =

<<120*55=6600>>6,600 feet. He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot 13,200 seconds is 13,2000 / 60 = <<13200/60=220>>220 minutes #### 220 Cristina, John, Clarissa and Sarah want to give their mother a photo album for her birthday. Cristina brings 7 photos, John brings 10 photos and Sarah brings 9 photos. If the photo album has 40 slots available, how many photos does Clarissa need to bring in order to complete the photo album? Excluding Clarissa, there are 7 + 10 + 9 = <<7+10+9=26>>26 photos. Clarissa needs to bring 40 – 26 = <<40-26=14>>14 photos to complete the photo album. #### 14 A school library has 120 books. Each student needs 5 books for their classes. The library was able to help 4 students on the first day of school, 5 students on the second day and 6 students on the third day. How many students can the library help out on the fourth day of school? On the first day, the library used 4 students * 5 books = <<4*5=20>>20 books. On the second day, the library used 5 students * 5 books = <<5*5=25>>25 books. On the third day, the library used 6 students * 5 books = <<6*5=30>>30 books. On the fourth day, the library had 120 books - 20 - 25 - 30 = <<120-20-25-30=45>>45 books remaining. The library can help 45 books / 5 books = <<45/5=9>>9 students on the fourth day. #### 9 Louie sells Dodge, Hyundai, and Kia vehicles, and his company has 400 vehicles for sale on the store's parking lot. Half of the vehicles on the lot are Dodge, and there are half as many Hyundai vehicles on the lot as there are Dodge vehicles. How many Kia vehicles are on the lot? Half of the 400 vehicles for sale on the lot are Dodges, or a total of 400/2=<<400/2=200>>200 Dodge vehicles. Since there are half as many Hyundai vehicles on the lot as there are Dodge vehicles, then there are 200/2=<<200/2=100>>100 Hyundai vehicles on the lot. Since the remainder of the vehicles are Kias, then there are 400-200-100=<<400-200-100=100>>100 Kia vehicles for sale on the lot. #### 100 20% of the job candidates at a temp agency have experience with Excel. 70% of the candidates are only willing to work day shifts. If a manager picks a candidate at random, what are the odds they know Excel and are willing to work nights? First find the percentage of candidates who are willing to work nights: 100% - 70% = 30% Then multiply that percentage by the percentage who know Excel to find the percentage who meet both qualifications: 30% * 20% = 6% #### 6 John goes to the store to buy Slurpees and gives them $20. Slurpees cost $2 each and he got $8 in change. How many Slurpees did he buy? He spent 20-8=$<<20-8=12>>12 on Slurpees So he got 12/2=<<12/2=6>>6 Slurpees #### 6 The bowl of fruit contains apples, pears, and bananas. There are two more pears than apples, and three more bananas than pears. If the bowl contains 19 pieces of fruit, how many bananas does it contain? Let A be the number of apples. There are A+2 pears. There are (A+2)+3 pears. Then A+(A+2)+((A+2)+3)=19. 3A+7=19 3A=12 A=4 There are 4 apples. There are (4+2)+3=<<4+2+3=9>>9 bananas. #### 9 Jeff bought 6 pairs of shoes and 4 jerseys for $560. Jerseys cost 1/4 price of one pair of shoes. Find the shoe's price total price. Let X be the shoe price. The jersey's price is 1/4*X. Jeff bought 6 pairs of shoes and 4 jerseys for 6*X + 4*(1/4X) = $560. Multiplying through the parentheses produces 6X + X = $560 Combining like terms produces 7X = $560 Dividing both sides by 7 produces X = $80, so the shoe price is $80 Since Jeff bought 6 pairs of shoes, he spent 80*6 = $<<80*6=480>>480 on shoes #### 480 Mrs. Garcia pays her insurance quarterly at $378. How much does she pay in a year for her insurance? Since there are three months in a quarter, then there are 12/3 = <<12/3=4>>4 quarters in a year. So, Mrs. Garcia pays $378 x 4 = $<<378*4=1512>>1512 in a year for her insurance. #### 1512 A cattle breeder owns 52 dairy cows. Each cow gives 1000 oz of milk per day. Calculate the amount of milk produced per week by the cows. Per day, the amount of milk produced is 1000*52 = <<1000*52=52000>>52000 oz. Per week, the amount of milk produced is 52000*7 = <<52000*7=364000>>364000 oz. #### 364000
