Matthew, the baker, arrives at work early every morning to make his famous caramel-apple coffee cakes for the day. It usually takes Matthew 1 hour to assemble ingredients, 1.5 hours to bake the cakes, and another 1 hour to decorate each cake with cinnamon sprinkles. One day, Matthew's oven failed to reach the correct temperature and it took twice as long for the cakes to bake as they usually take. On that day, how long did it take, in hours, for Matthew to make his famous caramel-apple coffee cakes?

Twice 1.5 hours is 2*1.5=

<<2*1.5=3>>3 hours. Thus, on that day, it took Matthew 1+3+1=<<1+3+1=5>>5 hours to make the cakes. #### 5 In 2021, Wayne is 37 years old. His brother Peter is 3 years older than him and their sister Julia is 2 years older than Peter. What year was Julia born in? Peter is 3 years older than Wayne who is 37 so Peter is 37+3 = <<37+3=40>>40 years old Julia is 2 years older than Peter who is 40 so Julia is 2+40 = <<2+40=42>>42 years old It's 2021 and Julia is 42 years old so she was born in 2021-42 = <<2021-42=1979>>1979 #### 1979 John decided to buy 10 pins for himself. They are normally $20 each but they were on sale for 15% off. How much did he spend on pins? The sell reduced the price of each pin by 20*.15=$<<20*.15=3>>3 So he paid 20-3=$<<20-3=17>>17 per pin So the total cost was 17*10=$<<17*10=170>>170 #### 170 Apple and peach trees are planted in the orchard of the Grange Poser farm. The orchard has 30 apple trees that each give 150 kg of apples and 45 peach trees that each produce an average of 65 kg of fruit. What is the total mass of fruit harvested in this orchard? Let’s first calculate what the apple trees produce: 30 trees * 150 kg/tree = <<30*150=4500>>4500 kg Then let's calculate what the peaches produce: 45 trees * 65 kg/tree = <<45*65=2925>>2925 kg We add these two masses: 4500 kg + 2925 kg = <<4500+2925=7425>>7425 kg #### 7425 Winston has 14 quarters. He then spends half a dollar on candy. How many cents does he have left? Winston has 350 cents because 14 x 25 = <<14*25=350>>350 He spends 50 cents because $1 / 2 = 50 cents He has 300 cents left at the end. #### 300 To get the printer to work, Jerry needs to add a black-and-white cartridge and three color cartridges. If each color cartridge costs $32 and each black-and-white cartridge costs $27, how much does he pay total? First find the total cost of the color cartridges: $32/cartridge * 3 cartridges = $<<32*3=96>>96 Then add the cost of the black-and-white cartridge to find the total cost: $96 + $27 = $<<96+27=123>>123 #### 123 A choir was singing a song that involved 30 singers. In the first verse, only half of them sang. In the second verse, a third of the remaining singers joined in. How many people joined in the final third verse that the whole choir sang together? In the first verse, 30 / 2 = <<30/2=15>>15 singers sang. In the second verse, 15 / 3 = <<15/3=5>>5 singers joined in. In the final verse, 30 - 15 - 5 = <<30-15-5=10>>10 singers joined for the whole choir to sing together. #### 10 Kimberly went strawberry picking with her family over the weekend. She picked 8 times the amount of strawberries her brother picked and her parents picked 93 strawberries less than her. If her brother picked 3 baskets each containing 15 strawberries, how many strawberries would they each have if they divide the total number of strawberries equally amongst them? Kimberly's brother picked 3 x 15 = <<3*15=45>>45 strawberries. Kimberly picked 8 x 45 = <<8*45=360>>360 strawberries. Kimberly's parents picked 360 - 93 = <<360-93=267>>267 strawberries. Altogether, they picked 45 + 360 + 267 = <<45+360+267=672>>672 strawberries. Each of them will have 672/4 = <<672/4=168>>168 strawberries. #### 168 Santino has 2 papaya trees and 3 mango trees. If each papaya tree produces 10 papayas and each mango tree produces 20 mangos, how many fruits does Santino have in total? Santino has 2 * 10 = <<2*10=20>>20 papaya fruits Santino has 3 * 20 = <<3*20=60>>60 mango fruits In total, Santino has 20 + 60 = <<20+60=80>>80 fruits #### 80 Jake amasses a fortune of 80 bitcoin. He donates 20 bitcoins to charity. He then gives half of all the bitcoins to his brother. After that, he triples the number of bitcoins he has. Then he donates another 10 coins. How many coins does he have? He had 80-20=<<80-20=60>>60 after the donation He kept 60/2=<<60/2=30>>30 after giving half to his brother So he has 30*3=<<30*3=90>>90 coins He then does 1 more donation and has 90-10=<<90-10=80>>80 coins left #### 80
