After 5 months, he has 8 bones available and has buried the rest. How many bones has he buried? How many bones does Barkley get every month? ** He gets 10 new bones, every month for 5 months so he has 10*5 = <<10*5=50>>50 dog bones How many bones has Barkley buried? ** He has 8 bones available which means he has buried 50-8 = <<50-8=42>>42 bones #### 42 Terry's mom brought home 4 different colored dogs from the shelter. The brown dog weighs 4 pounds. The black dog weighs 1 pound more than the brown dog. The white dog weighs twice as much as the brown dog. The grey dog weighs 2 pounds less than the black dog. What's the average weight of all the dogs? How much does the black dog weigh? ** Since the black dog weighs 1 pound more than the brown dog, the black dog weighs 1 + 4 = <<1+4=5>>5 pounds. How much does the white dog weigh? ** The white dog weighs 4 * 2 = <<4*2=8>>8 pounds. How much does the grey dog weigh? ** Because the grey dog weighs 2 pounds less than the black dog, the grey dog weighs 5 - 2 = <<5-2=3>>3 pounds. What is the total weight of all the dogs? ** The total weight of all dogs is 4 + 5 + 8 + 3 = <<4+5+8+3=20>>20 pounds. What is the average weight of all the dogs? ** The average weight of all the dogs is 20 / 4 = <<20/4=5>>5 pounds. #### 5 If it takes 10 people 10 days to shovel 10,000 pounds of coal, how many days will it take half of these ten people to shovel 40,000 pounds of coal? How many pounds of coal do the 10 people shovel in a day? ** The 10 people shovel 10,000 pounds per 10 days, or 10,000/10=<<10000/10=1000>>1000 pounds per day per 10 people. How many pounds of coal does each person shovel in a day? ** And 1000 pounds per day per 10 people is 1000/10=<<1000/10=100>>100 pounds per day per person. How many people are half of the ten people? ** Half of ten people is 10/2=<<10/2=5>>5 people. How many pounds of coal can 5 people shovel in a day? ** At 100 pounds per day per person, 5 people can shovel 5*100=<<5*100=500>>500 pounds per day. How many days will it take 5 people to shovel 40,000 pounds of coal? ** Therefore, for 5 people to shovel 40,000 pounds, it will take 40,000/500=<<40000/500=80>>80 days. #### 80 Mikaela earns $10 an hour tutoring. For the first month, she tutored for 35 hours and in the second month, she tutored 5 hours more than the first month. She spent 4/5 of her total earnings on her personal needs and saved the rest of the money. How much did she save? How many hours did Mikaela tutor in the second month? ** Mikaela spent 35 + 5 = <<35+5=40>>40 hours in the second month. How many hours did Mikaela tutor in the first two months? ** So, she tutored a total of 35 + 40 = <<35+40=75>>75 hours for the first two months. How much did Mikaela earn in the first two months? ** Thus, her total earning was 75 x $10 = $<<75*10=750>>750. How much did Mikaela spend in the first two months? ** And, her total expenses was 4/5 x $750 = $<<4/5*750=600>>600. How much did Mikaela save? ** Therefore, she saved an amount of $750 - $600 = $<<750-600=150>>150. #### 150 One serving of soup has 1 cup of vegetables and 2.5 cups of broth. How many pints of vegetables and broth combined would be needed for 8 servings? How many cups are in one serving? ** One serving = 1 + 2.5 = <<1+2.5=3.5>>3.5 cups How many cups are in 8 servings? ** Eight servings = 8 * 3.5 = <<8*3.5=28>>28 cups How many pints are in 8 servings? ** 28 cups = 14 pints How many pints of vegetables and broth combined would be needed for 8 servings? ** Eight servings would need 14 pints of vegetables and broth. #### 14 Five coworkers were talking during the lunch break. Roger, the oldest one, said that he has the same amount of experience in years as all four of the others combined and that his retirement should come when he accumulates 50 years of experience.

Robert said that he has 4 years of experience less than Peter but 2 more years of experience than Mike. How many more years does Roger have to work before he retires? How many years of experience does Peter have? ** Peter has 19 – 7 = <<19-7=12>>12 years of experience. How many years of experience does Robert have? ** Robert has 12 – 4 = <<12-4=8>>8 years of experience. How many years of experience does Mike have? ** Mike has 8 – 2 = <<8-2=6>>6 years of experience. How many years of experience does Tom have? ** Tom has 2 * 8 = <<2*8=16>>16 years of experience. How many years of experience does Roger have? ** Roger has 12 + 8 + 6 + 16 = <<12+8+6+16=42>>42 years of experience. How many years does Roger have to work before he retires? ** Roger has to work another 50 – 42 = <<50-42=8>>8 years before he retires. #### 8 Buying a toaster requires an insurance plan that is 20% of the MSRP, plus a mandatory state tax rate of 50% after the insurance plan calculation. Jon chooses to buy a toaster that costs $30 at MSRP. What is the total he must pay? How much is the insurance plan? ** The insurance plan costs $30*0.2=$<<30*0.2=6>>6. What is the total before the state tax? ** The pre-state tax total is $30+$6=$<<30+6=36>>36. How much is the state tax? ** State tax will be $36*0.5=$<<36*0.5=18>>18. What is the total he must pay? ** Jon needs to pay $18+$36=$<<18+36=54>>54 for his new toaster. #### 54 Tom originally was only able to lift 80 kg farmer handles per hand. After some training, he was able to double this number. He then decided to specialize and was able to get an extra 10%. How much weight can he hold in total? How much weight can Tom hold in total? ** After doubling he was able to hold 80*2=<<80*2=160>>160 kg per hand How much weight can Tom hold in total? ** Specialization gave him another 160*.1=<<160*.1=16>>16 kg How much weight can Tom hold in total? ** So he lifted 160+16=<<160+16=176>>176 kg per hand How much weight can Tom hold in total? ** That means he lifted a total of 352 kg #### 352 After eating half of the number of fruits he had, Martin remained with twice as many oranges as limes. If he has 50 oranges now, how many fruits did he initially have? How many limes does Martin have now? ** Since the number of oranges that Martin has now is twice the number of limes, there are 50/2 = <<50/2=25>>25 limes. How many fruits does Martin have now? ** The number of fruits she has now is 50 oranges+25 limes= <<50+25=75>>75 How many fruits did Martin initially have? ** If she had eaten half of the number of fruits that she had, initially Martin had 2*75 = <<2*75=150>>150 fruits #### 150
