Janet bought some muffins at the bakery. Each muffin is 75 cents. Janet paid $20 and got $11 in change back. How many muffins did Janet buy?

Janet paid with $20 and got back $11, so her muffins cost $20 - $11 = $

<<20-11=9>>9. Each muffin cost 75 cents, so she bought 9/.75 = <<9/.75=12>>12 muffins #### 12 It cost 50 dollars to get cats ready for adoption, 100 dollars to get adult dogs ready for adoption, and 150 to get puppies ready for adoption. If 2 cats, 3 adult dogs, and 2 puppies are adopted what was the cost to get them ready? The cost to get the cats ready is 2*50=$<<2*50=100>>100 The cost to get adult dogs ready is 3*100=$<<3*100=300>>300 The cost to get puppies ready is 2*150=$<<2*150=300>>300 The total cost is 300+300+100=$<<300+300+100=700>>700 #### 700 Hannah brought $30 to the county fair.

On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him? Carl saved in 6 weeks $25/week x 6 weeks = $<<25*6=150>>150 On the seventh week, he ended up having to pay in bills $150/3 = $<<150/3=50>>50 His savings were then $150 - $50 = $<<150-50=100>>100 His dad gave him $170 – $100 = $<<170-100=70>>70 #### 70 John has 10 members of his family on his father's side. His mother's side is 30% larger. How many people are there in total? His mother's side is 10*.3=<<10*.3=3>>3 people larger than his father's side So his mother's side has 10+3=<<10+3=13>>13 people So the total number of people is 13+10=<<13+10=23>>23 #### 23 Anthony keeps a bottle of vinegar in his cupboard for 2 years. Each year 20% of the vinegar evaporates. What percent of the vinegar is left after 2 years? First find what percent of the vinegar is still in the bottle after each year: 100% - 20% = 80% Then multiply the amount of vinegar left after one year by the percentage left after each year to find how much is left after 2 years: 80% * 80% = 64% #### 64 My cat's empty bowl weighs 420 grams. If I give my cat 60 grams per day and I always fill her bowl every 3 days, how much does her bowl weigh if after I ended up refilling her empty bowl she only ate 14 grams? If I give my cat 60 grams per day and I fill it to last 3 days, then I put a total of 60*3 = <<60*3=180>>180 grams into her bowl If the empty bowl weighs 420 grams and I put 180 grams the total weight is = 420+180 = <<420+180=600>>600 grams If my cat only ate 14 grams then the bowl right now weighs 600-14 = <<600-14=586>>586 grams #### 586 Benjie is five years older than Margo. If Benjie is 6 years old, how old will Margo be in three years? Margo is 6 - 5 = <<6-5=1>>1 year old now. So, Margo will be 1 + 3 = 4 years old in three years. #### 4 Barkley gets 10 new dog bones at the beginning of the month. After 5 months, he has 8 bones available and has buried the rest. How many bones has he buried? He gets 10 new bones, every month for 5 months so he has 10*5 = <<10*5=50>>50 dog bones 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? Since the black dog weighs 1 pound more than the brown dog, the black dog weighs 1 + 4 = <<1+4=5>>5 pounds. The white dog weighs 4 * 2 = <<4*2=8>>8 pounds. Because the grey dog weighs 2 pounds less than the black dog, the grey dog weighs 5 - 2 = <<5-2=3>>3 pounds. The total weight of all dogs is 4 + 5 + 8 + 3 = <<4+5+8+3=20>>20 pounds. The average weight of all the dogs is 20 / 4 = <<20/4=5>>5 pounds. #### 5
