Jerry is trying to cut down on the amount of soda he drinks. Right now, he drinks 48 sodas a week. If he cuts the number of sodas he drinks in half each week, how many weeks will it take him to only drink 6 sodas per week?

Figure out how many sodas Jerry drinks after 1 week by dividing the starting number of sodas by 2: 48 sodas / 2 =

<<48/2=24>>24 sodas Now repeat the process to figure out how many soda he drinks after 2 weeks: 24 sodas / 2 = <<24/2=12>>12 sodas Repeat the process one more time to find the number of sodas after 3 weeks: 12 sodas / 2 = <<12/2=6>>6 sodas. It takes Jerry 3 weeks to get down to 6 sodas. #### 3 Jefferson hires a carriage to go to the church. It is 20 miles away. The horse can go 10 miles per hour. It cost $30 per hour plus a flat fee of $20. How much did he pay for the carriage? He paid for 20/10=<<20/10=2>>2 hours That means the hourly fee was 30*2=$<<30*2=60>>60 So the total cost was 60+20=$<<60+20=80>>80 #### 80 In Sam's collection, there are ten more black pens than blue pens and twice as many blue pens as pencils. There are also eight pencils and two fewer red pens than pencils. How many pens in all are there in Sam's collection? 8 x 2 = <<8*2=16>>16 are blue pens. 16 + 10 = <<16+10=26>>26 are black pens. 8 - 2 = <<8-2=6>>6 are red pens. Therefore, there are 16 + 26 + 6 = <<16+26+6=48>>48 pens in all in Sam's collection. #### 48 Joseph gave 23 cards to each of his 15 students and had 12 cards left. How many cards did Joseph have at first? He gave 23 cards each to 15 students for a total of 23*15 = <<23*15=345>>345 cards He has 12 cards left, so originally the number of cards was 345+12 = 357 cards #### 357 Mr. Lalande inherited 20,000 euros from his old aunt Adeline. He is very happy because he will be able to afford the car of his dreams, a superb car worth 18000 €. He goes to the dealership and tries the car. He decides to take it, but instead of paying for everything right away, he chooses to pay in several installments. He pays 3,000 euros to be able to leave with the car and the seller offers to let him pay the rest in 6 monthly installments. How much does Mr. Lalande have to pay every month? Let’s first calculate what remains to be paid to Mr. Lalande once he leaves the store 18000 - 3000 = <<18000-3000=15000>>15000£ Let’s split this sum into 6 month installments: 15000 / 6 = <<15000/6=2500>>2500£ #### 2500 A tank with a capacity of 8000 gallons is 3/4 full. Daxton empty's the tank by 40% of the total volume of water in the tank to water his vegetable farm. He then fills the tank with 30% of the volume of water remaining in the tank. Calculate the final volume of water in the tank. The volume of water that is in the tank initially is 3/4*8000 = <<3/4*8000=6000>>6000 gallons. When Daxton empties 40% of the water, he pumps out 40/100*6000 = <<2400=2400>>2400 gallons of water. The total volume of water remaining in the tank is 6000-2400 = <<6000-2400=3600>>3600 gallons. Daxton then fills the tank with 30/100*3600 = <<30/100*3600=1080>>1080 gallons of water. The final volume of water in the tank is 3600+1080 = <<3600+1080=4680>>4680 gallons. #### 4680 Angel has written letters to all of her pen pals and is putting all of the letters in envelopes. Most of the letters are put into large envelopes and the remaining 20 letters are put into small envelopes. The large envelopes each contain 2 letters each. If Angel has written a total of 80 letters, how many large envelopes did she use? As some of the letters are in small envelopes, there must be 80 total letters – 20 letters in small envelopes = <<80-20=60>>60 letters in large envelopes. Angel therefore used 60 letters / 2 letters per large envelope = <<60/2=30>>30 large envelopes. #### 30 James buys 100 tennis balls and gives half of them away. The other half he puts into 5 large containers. How many tennis balls go in each container? He keeps 100/2=<<100/2=50>>50 tennis balls So 50/5=<<50/5=10>>10 go in each container #### 10 Bob buys nose spray. He buys 10 of them for a "buy one get one free" promotion. They each cost $3. How much does he pay? He got 10/2=<<10/2=5>>5 paid That means he paid 5*3=$<<5*3=15>>15 #### 15 Ben has two brothers. They can each eat 12 slices of pizza. They are ordering pizza for the night and want to make sure they get enough. The large pizzas have 14 slices and the small pizzas have 8. If they order 1 small pizza, how many large pizzas do they need to order? They need 36 slices because 3 x 12 = <<3*12=36>>36 After ordering the small, they need 28 slices because 36 -8 = <<28=28>>28 They need 2 large pizzas because 28 / 14 = <<28/14=2>>2 #### 2
