Tonya is in a hamburger eating contest. Each hamburger is 4 ounces. Last year the winner ate 84 ounces. How many hamburgers does she have to eat to beat last year's winner?

Last year's winner ate 21 hamburgers because 84 / 4 =

<<84/4=21>>21 She needs to eat 22 hamburgers because 21 + 1 = <<21+1=22>>22 #### 22 A restaurant buffet has 36 different dishes available to try. The restaurant features mango salsa on three of its dishes, fresh mangoes in a sixth of its dishes, and mango jelly in one dish. Oliver despises mangoes and won't eat them, but can pick them out of two of the dishes with fresh mango that he would be willing to try. How many dishes are left for Oliver on the buffet? There are fresh mangos in 36 / 6 = <<36/6=6>>6 dishes. Thus, there are 3 + 6 + 1 = <<3+6+1=10>>10 dishes with mango on the buffet. Oliver can pick the mango out of 2 of the dishes, so there are 10 - 2 = <<10-2=8>>8 dishes he won't eat. Thus, there are 36 - 8 = <<36-8=28>>28 dishes left for Oliver on the buffet. #### 28 While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all? If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = <<20+100=120>>120 carriages. Together, Flying Scotsman and Norwich had 120 +100 = <<120+100=220>>220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = <<130-20=110>>110 carriages. Together, Euston and Norfolk had 110 + 130 = <<110+130=240>>240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = <<240+220=460>>460 carriages. #### 460 Sandy's goal is to drink 3 liters of water in a day. She drinks 500 milliliters of water every after 2 hours. After how many hours will she be able to drink a total of 3 liters of water? Since there are 1000 milliliters in 1 liter, then 3 liters is equal to 3 x 1000 = <<3*1000=3000>>3000 milliliters. She needs to drink 3000/500 = <<3000/500=6>>6 sets of 500 milliliters of water. So, she will be able to drink a total of 3 liters after 6 sets x every 2 hours = 12 hours. #### 12 Jenna runs a wholesale business. She pays $3 for each widget and resells it for $8. Every month she has to pay $10,000 in rent, 20% of her total profit in taxes, and $2,500 each to four workers. If Jenna sells 5000 widgets one month, how much is her total profit or loss? First calculate how much Jenna spends on salaries: $2,500 * 4 = $<<2500*4=10000>>10,000 Next find Jenna's total fixed costs by adding the cost of salaries and rent: $10,000 + $10,000 = $<<10000+10000=20000>>20,000 Next calculate how much profit Jenna makes on each widget by subtracting the cost from the sale price: $8 - $3 = $<<8-3=5>>5 Now multiply the profit per widget by the number of widgets sold: $5 * 5000 = $<<5*5000=25000>>25,000 Now subtract Jenna's costs from her sales to find her total profit before taxes: $25,000 - $20,000 = $<<25000-20000=5000>>5,000 Now multiply Jenna's profit by her 20% tax rate to find how much she owe in taxes: $5,000 * .2 = $<<5000*.2=1000>>1,000 Now subtract Jenna's taxes from her profit before taxes to find her total profit: $5,000 - $1,000 = $<<5000-1000=4000>>4,000 #### 4000 It takes 3 beehives to make enough wax to make 12 candles. How many hives does it take to make 96 candles? First find the number of candles produced per hive: 12 candles / 3 hives = <<12/3=4>>4 candles/hive Then divide the total number of candles by the number of candles per hive to find the number of hives: 96 candles / 4 candles/hive = <<96/4=24>>24 hives #### 24 Rosalina receives gifts from three people on her wedding day. How many gifts did she get if Emilio gave 11 gifts, Jorge gave 6 gifts, and Pedro gave 4 gifts? If Emilio presents 11 gifts and Jorge 6 gifts, together they have presented 11+6=<<11+6=17>>17 gifts. If Pedro also gives Rosalinda 4 gifts, Rosalinda's total number is 17+4 = <<17+4=21>>21 gifts. #### 21 Kate has to fill 52 balloons for the party. Each balloon holds 5 gallons of air. For the first 10 minutes, she can fill the balloons at a rate of 8 gallons of air per minute. For the next five minutes, she fills them at half that rate. After that, she fills the rest of the balloons at a rate of 2 gallons of air per minute. How many minutes will it take her to fill all of the balloons? She needs to fill a total of 52 * 5 = <<52*5=260>>260 gallons of air. In the first ten minutes, she fills 8 * 10 = <<8*10=80>>80 gallons of air. For the next five minutes, she fills 8 / 2 * 5 = <<8/2*5=20>>20 gallons of air. That leaves her with 260 - 80 - 20 = <<260-80-20=160>>160 gallons of air to fill. It will take her 160 / 2 = <<160/2=80>>80 more minutes to fill the rest of the balloons. The total time to fill all of the balloons is 10 + 5 + 80 = <<10+5+80=95>>95 minutes. #### 95 Lisa is making a pizza. She uses 30 pieces of pepperoni for a pizza, twice as many pieces of ham, and 12 more pieces of sausage than pepperoni. If there are 6 slices of pizza, and everything was distributed evenly, how many pieces of meat altogether are on each slice? There are 30*2 = <<30*2=60>>60 pieces of ham put on the pizza. There are 30+12 = <<30+12=42>>42 pieces of sausage put on the pizza. There are 30/6 = <<30/6=5>>5 pieces of pepperoni on each pizza slice. There are 60/6 = <<60/6=10>>10 pieces of ham on each pizza slice. There are 42/6 = <<42/6=7>>7 pieces of sausage on each pizza slice. There are 5+10+7 = <<5+10+7=22>>22 pieces altogether on each slice of pizza. #### 22 Matt has a peanut plantation that is 500 feet by 500 feet. 1 square foot of peanuts can make 50 grams of peanuts. If it takes 20 grams of peanuts to make 5 grams of peanut butter and 1 kg of peanut butter sells for $10 how much does he make from his plantation? His plantation is 500*500=<<500*500=250000>>250,000 square feet That means he gets 250,000*50=<<250000*50=12500000>>12,500,000 grams of peanuts So he makes 12,500,000*5/20=<<12500000*5/20=3125000>>3,125,000 grams of peanut butter So he has 3,125,000/1000=<<3125000/1000=3125>>3125 kg of peanut butter That means it sells for 3125*10=$<<3125*10=31250>>31,250 #### 31250
