Without factoring in the cost of depreciation for his car John made $30,000 doing Uber. When he finally traded in the car he bought for $18,000 he got $6000 back. What was his profit from driving Uber?

His car depreciated 18000-6000=$

<<18000-6000=12000>>12000 So he made a profit of 30000-12000=$<<30000-12000=18000>>18000 #### 18000 Zoe wants to go on the field trip to Washington DC with her middle school this spring and the cost is $485. Her grandma gave her $250 toward her fees and she must earn the rest by selling candy bars. She makes $1.25 for every candy bar she sells. How many candy bars does Zoe need to sell to earn the money for the trip? Since Zoe’s grandma gave her some money toward her trip, she needs to come up with $485 – $250 = $<<485-250=235>>235. This means she must sell $235 / $1.25/candy bar = <<235/1.25=188>>188 candy bars. #### 188 Henley bought 300 candies and shared them with her two brothers. However, they realized 40% of them were sour, and they had to separate those out. If they then shared the good candies equally, how many candies did each get? If the number of candies was 300, and 40% percent were sour, then there were 40/100*300 =<<40/100*300=120>>120 sour candies. The number of good candies was 300-120=<<300-120=180>>180 The number of people who received candy is Henley, 1+ 2 brothers = <<1+2=3>>3 people if they divided the good candies equally, each person got 180/3 = <<180/3=60>>60 candies. #### 60 A store decides to shut down and sell all of its inventory. They have 2000 different items which would normally retail for $50. They are offering an 80% discount and manage to sell 90% of the items. They owed $15000 to their creditors. How much money do they have left after the sale? They sold 2000*.9=<<2000*.9=1800>>1800 items They offered a 50*.8=$<<50*.8=40>>40 discount That means that each item sold for 50-40=$<<50-40=10>>10 So they made 1800*10=$<<1800*10=18000>>18,000 So they had 18,000-15,000=$<<18000-15000=3000>>3,000 leftover #### 3000 Ben's potato gun can launch a potato 6 football fields. If a football field is 200 yards long and Ben's dog can run 400 feet/minute, how many minutes will it take his dog to fetch a potato he launches? First find the total distance the potato flies in yards: 200 yards/field * 6 fields = 1200 yards Then multiply that number by the number of feet per yard to convert it to feet: 1200 yards * 3 feet/yard = <<1200*3=3600>>3600 feet Then divide that number by the dog's speed to find the number of minutes it has to run to fetch the potato: 3600 feet / 400 feet/minute = <<3600/400=9>>9 minutes #### 9 During a staff meeting, 50 doughnuts were served. If each of the 19 staff ate 2 doughnuts, how many doughnuts are left? The staff had eaten a total of 19 x 2 = <<19*2=38>>38 doughnuts. So, 50 - 38 = <<50-38=12>>12 doughnuts are left. #### 12 Al is 25 pounds heavier than Ben. Ben is 16 pounds lighter than Carl. If Ed weighs 146 pounds and is 38 pounds lighter than Al, find the weight of Carl. Al weighs 146 + 38 = <<146+38=184>>184 pounds. Ben weighs 184 - 25 = <<184-25=159>>159 pounds. Carl weighs 159 + 16 = <<159+16=175>>175 pounds. #### 175 Kylie has 34 stamps in her collection. Her friend, Nelly, has 44 more stamps than Kylie. How many stamps do Kylie and Nelly have together? Nelly has 34 + 44 = <<34+44=78>>78 stamps. Thus, Kylie and Nelly have 34 + 78 = <<34+78=112>>112 stamps. #### 112 The price of a book was $400. If the book's price is decreased by 15% and then increased by 40%, what is the final price of the book? When the price of the book is decreased by 15%, the total price decrease is 15/100*$400=$<<15/100*400=60>>60 The new price of the book becomes $400-$60 = $<<400-60=340>>340 The price of the book is then increased by 40/100*340 = $<<40/100*340=136>>136 The final price of the book is $340+$136 = $<<340+136=476>>476 #### 476 Alex and his friend had a free throw contest. Alex made 8 baskets. Sandra made three times as many baskets as Alex and Hector made two times the number of baskets that Sandra made. How many baskets did they make in total? Sandra made 3*8=<<3*8=24>>24 baskets Hector made 24*2=<<24*2=48>>48 baskets. In total they made 8+24+48= <<8+24+48=80>>80 baskets #### 80
