Jonah decided to set up an aquarium. He started with 14 small fish. He added 2 more, but they ate 6 of his original fish before he could remove them and take them back to the store. He exchanged them for 3 new fish. How many fish does Jonah have now?

Jonah started with 14 fish + 2 more =

<<14+2=16>>16 fish. Of the 16 fish – 6 were eaten – 2 were returned to the store = 8 fish. After he returned the fish to the store, he exchanged them for 3 new fish + 8 fish that were left = <<3+8=11>>11 fish now in his tank. #### 11 Jaylen’s dog eats 1 cup of dog food in the morning and 1 cup of dog food in the evening. If she buys a bag that has 32 cups of dog food, how many days can she feed her dog with it? Every day, Jaylen’s dog eats 1 x 2 = <<1*2=2>>2 cups of dog food. The bag will feed her dog for 32 / 2 = <<32/2=16>>16 days. #### 16 It’s February 2021. Mark was born in January 1976. Graham is 3 years younger than Mark, and Graham’s sister, Janice, is 1/2 the age of Graham. How old is Janice? It’s 2021 and Mark was born in 1976 so Mark is 2021-1976 = <<2021-1976=45>>45 years old Graham is 3 years younger than Mark who is 45 so Graham is 45-3 = 42 years old Janice is 1/2 the age of Graham who is 42 so Janice is 42/2 = <<42/2=21>>21 years old #### 21 A house’s living room, dining room and kitchen take up 1,000 sq ft. The house also has a guest bedroom and a master bedroom suite. If the guest bedroom is a quarter of the size of the master bedroom suite, and the house is 2,300 sq ft total, how large is the master bedroom suite? The house is 2,300 sq ft and we know the non-bedroom sections take up 1,000 sq ft, so that leaves 2300-1000 = <<2300-1000=1300>>1,300 sq ft for the bedrooms/bathrooms Let x be the size of the master bedroom suite. Then the guest bedroom is 0.25x. So together the bedrooms are x + 0.25x = 1.25x in size. This means 1.25x = 1300 So x = 1300 / 1.25 = <<1300/1.25=1040>>1040 sq ft #### 1040 Antonella has ten Canadian coins in her purse that are either loonies or toonies. A loonie equals $1 and a toonie equals $2. If she bought a $3 Frappuccino and still has $11, how many toonies did she initially have? If Antonella spent $3 and now has $11, that means initially she had $3 + $11 = $<<3+11=14>>14 Let the number of loonies Antonella had be L and the number of toonies be T. Initially she had in her purse a total of 1L + 2T = $14 We also know that she had 10 coins in total or 10=L+T That means initially she had T=10-L toonies Combining both equations we know that 14=1L+2*(10-L) If we multiply through the parentheses, we get 14=1L+20-2L If we combine the variables on one side and the constants on another, we get -6=-1L or L=6 Knowing the value of L, we can solve for T= 10 - L = 10 - 6 = <<10-6=4>>4 #### 4 Leila and Mohamed decided to donate their old toys to a children’s home. Leila gave 2 bags with 25 toys in each bag. Mohamed’s donation was 3 bags with 19 toys in each bag. How many more toys did Mohamed donate? Leila gave 2 * 25 = <<2*25=50>>50 toys Mohamed’s donation was 3 * 19 = <<3*19=57>>57 toys The difference is 57 - 50 = <<57-50=7>>7 toys Mohamed therefore donated an additional 7 toys. #### 7 John decides to get a new phone number and it ends up being a recycled number. He used to get 20 text messages a day. Now he is getting 55. Assuming the number of texts his friends send has not changed, how many text messages per week is he getting that are not intended for him? He is getting an extra 55-20=<<55-20=35>>35 text messages per day So he is getting an extra 35*7=<<35*7=245>>245 text messages per week #### 245 Jason is hiring two construction workers, one electrician and one plumber. If the construction workers each make $100/day, the electrician makes double what a worker is paid and the plumber makes 250% of a worker's salary, how much are the overall labor costs for one day? First find how much the electrician earns per day: $100/day * 2 = $<<100*2=200>>200/day Then find how much the plumber earns per day: $100/day * 250% = $<<100*250*.01=250>>250/day Then find how much both workers pay together: $100/day/worker * 2 workers = $<<100*2=200>>200/day Then add the cost of each worker to find the total labor cost per day: $200/day + $250/day + $200/day = $<<200+250+200=650>>650/day #### 650 Flynn watches 30 minutes of tv every night during the weekdays. On the weekends, she watches an additional 2 hours of TV in total. How many hours of tv does she watch in 52 weeks? She watches 30 minutes of tv per night, 5 days a week so that's 30*5 = <<30*5=150>>150 minutes of tv She watches 2 hours of tv on the weekends and 60 minutes are in 1 hour so that's 2*60 = <<2*60=120>>120 minutes of tv All total she watches 150+120 = <<150+120=270>>270 minutes of tv per week There are 52 weeks in a year and she watches 270 minutes per week so that's 52*270 = <<52*270=14040>>14,040 minutes of tv per year She watches 14,040 minutes of tv and 60 minutes are in an hour so she watches 14040/60 = <<14040/60=234>>234 hours #### 234 Linda is building a new hotel with two wings. The first wing has 9 floors and each floor has 6 halls each with 32 rooms. The second wing has 7 floors each with 9 halls with 40 rooms each. How many rooms are in the hotel total? First find the number of rooms per floor in the first wing: 32 rooms/hall * 6 halls/floor = <<32*6=192>>192 rooms/floor Then find the total number of rooms in the first wing by multiplying that number by the number of floors: 192 rooms/floor * 9 floors = <<192*9=1728>>1728 rooms Then find the number of rooms per floor in the second wing: 40 rooms/hall * 9 halls/floor = <<40*9=360>>360 rooms/floor Then find the total number of rooms in the second wing by multiplying that number by the number of floors: 360 rooms/floor * 7 floors = <<360*7=2520>>2520 rooms Then add the total number of rooms in each wing to find the overall total: 1728 rooms + 2520 rooms = <<1728+2520=4248>>4248 rooms #### 4248
