Carter has a 14-hour road trip. He wants to stop every 2 hours to stretch his legs. He also wants to make 2 additional stops for food and 3 additional stops for gas. If each pit stop takes 20 minutes, how many hours will his road trip become?

He has a 14-hour trip and wants to stop every 2 hours so that's 14/2 =

<<14/2=7>>7 pit stops He will make 7 pit stops plus 2 more for food and 3 more for gas for a total of 7+2+3 = <<7+2+3=12>>12 pit stops Each pit stop will take 20 minutes and he is making 12 stops so that's 20*12 = <<20*12=240>>240 minutes 60 minutes are in an hour and he's adding 240 minutes to his trip so that's 240/60 = <<240/60=4>>4 more hours His trip started as 14 hours and he will add an additional 4 hours in pit stops for a total of a 14+4 = <<14+4=18>>18 hour long trip #### 18 Jenson and Kingsley have a tailoring business. Jenson makes 3 shirts, and Kingsley makes 5 pairs of pants per day. If each shirt uses 2 yards of fabric and a pair of pants uses 5 yards of fabric, how many yards of fabric do they need every 3 days? Jenson uses 2 x 3 = <<2*3=6>>6 yards of fabric for making shirts every day. Kingsley uses 5 x 5 = <<5*5=25>>25 yards of fabric every day for making pair of pants. So, the total yards of fabric they use per day is 25 + 6 = <<25+6=31>>31 Therefore, the total yards of fabric they use every 3 days is 31 x 3 = <<31*3=93>>93. #### 93 The swimming club went to a swim meet in another town. They took 2 cars and 3 vans. There were 5 people in each car and 3 people in each van. Each car can hold a maximum of 6 people and each van can hold a maximum of 8 people. How many more people could have ridden with the swim team? The available number of people in each car is 6 * 2 cars = <<6*2=12>>12 people. The available number of people in each van is 8 * 3 vans = <<8*3=24>>24 people. The total number of people that could go with the team is 12 people + 24 people = <<12+24=36>>36 people. The team took with them 2 cars * 5 people = <<2*5=10>>10 people. The team also took 3 vans * 3 people = <<3*3=9>>9 people. The team brought 10 people + 9 people =<<10+9=19>>19 people. The team could bring an additional 36 people - 19 people = <<36-19=17>>17 people. #### 17 A bird watcher records the number of birds he sees each day. One Monday he sees 70 birds. On Tuesday he sees half as many birds as he did on Monday. On Wednesday he sees 8 more birds than he did on Tuesday. How many total birds did the bird watcher see from Monday to Wednesday? Monday:70 Tuesday:70/2=<<70/2=35>>35 Wednesday:35+8=<<35+8=43>>43 Total:70+35+43=<<70+35+43=148>>148 birds #### 148 The price of a math textbook in the school bookshop is $45. If those sold in bookshops outside the school cost 20% less, how much can Peter save by buying from other bookshops rather than the school's if he wants to buy 3 math textbooks? 20% of $45 is (20/100)*$45 = $<<(20/100)*45=9>>9 The price of the textbook in other bookshops cost $9 less than $45 which is $45-$9 = $<<45-9=36>>36 Three textbooks from the school bookshop would cost $45*3 = $<<45*3=135>>135 Three textbooks from another bookshop would cost $36*3 = $<<36*3=108>>108 Peter can save $135-$108 = $<<135-108=27>>27 by buying from another bookshop #### 27 John and his two brothers decide to split the cost of an apartment. It is 40% more expensive than John's old apartment which costs $1200 per month. How much does John save per year by splitting the apartment compared to living alone? His old apartment cost 1200*12=$<<1200*12=14400>>14,400 per year His new apartment 1200*1.4=$<<1200*1.4=1680>>1680 per month That means it cost 1680/3=$<<1680/3=560>>560 per month So it cost 560*12=$<<560*12=6720>>6720 So he saves 14400-6720=$<<14400-6720=7680>>7680 #### 7680 At school today, Charlize was 20 minutes late. Four of her classmates were each ten minutes late than she was. What's the total time for which the five students were late? If Charlize was 20 minutes late, each of her friends was 20+10 = <<20+10=30>>30 minutes late. The total time for which Charlize's friends were late was 4*30= <<4*30=120>>120 minutes. Together with Charlize, the three friends were 120+20 = <<120+20=140>>140 minutes late. #### 140 Sheena is sewing the bridesmaid’s dresses for her sister’s wedding. She can sew one dress in 12 hours. There are 5 bridesmaids in the wedding. If Sheena sews the dresses 4 hours each week, how many weeks will it take her to complete them? It will take Sheena 12 hours x 5 bridesmaids = <<12*5=60>>60 hours to sew the dresses. It will take her 60 hours / 4 hours = <<60/4=15>>15 weeks. #### 15 Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have? Let X be the amount of money Sarah has, so Bridget has X + 50 cents We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300 We therefore know that 2X = 250 So Sarah has 250 / 2 = <<250/2=125>>125 cents #### 125 Mitzi brought $75 to the amusement park. She spent $30 on a ticket, $13 on food, and $23 on a T-shirt. How much money does she have left? Mitzi spent a total of $30 + $13 + $23 = $<<30+13+23=66>>66. So she still has $75 - $66 = $<<75-66=9>>9 left. #### 9
