Tyler has 21 CDs. He gives away a third of his CDs to his friend. Then he goes to the music store and buys 8 brand new CDs. How many CDs does Tyler have now?

Tyler gives away 21 / 3 =

<<21/3=7>>7 CDs After giving away a third of his CDs, Tyler has 21 - 7 = <<21-7=14>>14 CDs After buying new CDs, Tyler has 14 + 8 = <<14+8=22>>22 CDs #### 22 Steve owns a lake shop that sells fish. He has a stock of 200 fish. He sells 50 fish and because his refrigerators stop working a third of the remaining fish become spoiled. A new stock of 200 more fish arrives. How many fish does he have in stock now? If he had 200 fish and sells 50, he is left with 200 - 50 = <<200-50=150>>150 fish If a third of them get spoiled 1/3 * 150 = <<150*1/3=50>>50 fish get spoiled The remaining number of fish is now 150 - 50 = <<150-50=100>>100 He then gets 200 more to make 100 + 200 = <<100+200=300>>300 fish #### 300 Tabitha and her friends were excited to go to the Christmas parade because they knew candy would be thrown to the crowd from the floats. Tabitha caught 22 pieces of candy. Stan caught 13 pieces. Julie caught half the amount of candy as Tabitha caught and Carlos caught twice as much candy as Stan. How many pieces in total did the friends catch? Julie caught half the amount of Tabitha's 22 pieces so 22/2 = <<22/2=11>>11 pieces of candy caught by Julie Carlos caught twice the amount of candy as Stan's 13 pieces so 2 * 13 = <<2*13=26>>26 pieces of candy caught by Carlos All together, Tabitha caught 22 pieces, Stan had 13, Julie had 11 and Carlos had 26, so there were a total of 22+13+11+26 = <<22+13+11+26=72>>72 pieces of candy #### 72 Tom cannot afford a normal doctor, so he goes to a discount clinic that is 70% cheaper. It takes two visits, though, instead of 1. A normal doctor charges $200 for a visit. How much money does he save? Each of Tom's visits was 200*.7=$<<200*.7=140>>140 cheaper So he paid $200 - $140 = $<<200-140=60>>60 per visit That means he paid $60 * 2 = $<<60*2=120>>120 So he saved $200 - $120 = $<<200-120=80>>80 #### 80 Every Sunday, Sean picks up 1 almond croissant and 1 salami and cheese croissant that are $4.50 each. He also grabs a plain croissant for $3.00 and a loaf of focaccia for $4.00. On his way home he stops and picks up 2 lattes for $2.50 each. How much did he spend? The almond croissant and the salami and cheese croissant are $4.50 each so that's 2*4.50 = $9.00 He buys 2 lattes that are $2.50 each so that's 2*2.50 = $<<2*2.50=5.00>>5.00 The flavored croissants are $9.00, the lattes are $5.00 and he also grabbed a plain croissant for $3.00 and focaccia for $4.00 for a total of 9+5+3+4 = $<<9+5+3+4=21.00>>21.00 #### 21 Bingley has 5 bracelets. Kelly gives Bingley a fourth of her 16 bracelets. Then Bingley gives a third of his bracelets to his little sister. How many bracelets does Bingley have remaining? Kelly gives Bingley 16 / 4 = <<16/4=4>>4 bracelets Bingley has 5 + 4 = <<5+4=9>>9 bracelets Bingley gives his little sister 9 / 3 = <<9/3=3>>3 bracelets In the end, Bingley has 9 - 3 = <<9-3=6>>6 bracelets remaining #### 6 Matt needs to buy new plates for his home. He only wants to do dishes once a week. Three days a week it is only him and his son eating and they use 1 plate each. On the remainder of the days, his parents join them and everyone uses 2 plates that day. How many plates does he need to buy? So for 3 of the days, there are 1+1=2 people eating So for those days they use 3*2=<<3*2=6>>6 plates On 7-3=4 days the parents join them On those days there are 2+2=<<2+2=4>>4 people eating They use 4*2=<<4*2=8>>8 plates So they use 8*4=<<8*4=32>>32 plates That means they use a total of 32+6=<<32+6=38>>38 plates #### 38 Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week? She uses 3 ounces of beans per day because 2 x 1.5 = <<2*1.5=3>>3 She uses 21 ounces of beans per week because 7 x 3 = <<7*3=21>>21 She buys 2 bags of beans per week because 21 / 10.5 = <<21/10.5=2>>2 She spends $16 on the beans per week because 2 x 8 = <<16=16>>16 She spends $2 on the milk per week because 4 x (1/2) = <<4*(1/2)=2>>2 She spends $18 per week on her coffee because 16 + 2 = <<16+2=18>>18 #### 18 On Sunday Trey is going to do some chores at home. First, he wants to make a To Do list and count up how many things he has to do that day and how long it should take. He has several items under 'clean the house,' 'take a shower' and then 'make dinner.' In total there are 7 things to do to clean the house; 1 thing to do to take a shower; and 4 things to do to make dinner. If everything on Trey's list takes 10 minutes to do, how many hours total will it take to complete Trey's list? On Trey's list there are 7 + 1 + 4 things to do = <<7+1+4=12>>12 things to do in total. Each thing takes 10 minutes to do, so 10 minutes x 12 things = <<10*12=120>>120 minutes. An hour has 60 minutes in it, so 120 minutes / 60 minutes in an hour = <<120/60=2>>2 total hours it will take Trey to complete his list. #### 2 James decides to build a tin house by collecting 500 tins in a week. On the first day, he collects 50 tins. On the second day, he manages to collect 3 times that number. On the third day, he collects 50 tins fewer than the number he collected on the second day. If he collects an equal number of tins on the remaining days of the week, what's the number of tins he collected each day for the rest of the week? On the second day, he collected 3 times the number of tins he collected on the first day, which is 3*50 = <<3*50=150>>150 tins. On the third day, he collected 50 tins fewer than the second day, which is 150-50 = <<150-50=100>>100 tins The total for the three days is 150+100+50 = <<150+100+50=300>>300 tins. To reach his goal, he still needs 500-300 = <<500-300=200>>200 tins. Since the total number of days left in the week is 4, he'll need to collect 200/4 = <<200/4=50>>50 tins per day to reach his goal #### 50
