3 families of 4 people shared a vacation rental for 7 days. Everyone uses 1 oversized beach towel a day before getting a new one. The washing machine can hold 14 oversized beach towels per load. How many loads of laundry will it take to wash all the oversized beach towels?

How many people are in the vacation rental? ** There are 3 families of 4 meaning there are 3*4 =

<<3*4=12>>12 people in the vacation rental How many towels do the 12 people use in a day? ** They all use 1 oversized beach towel a day so they use 1*12 = <<1*12=12>>12 towels a day How many towels do the 12 people use in a week? ** They use 12 towels a day for 7 days so in one week they use 12*7 = <<12*7=84>>84 beach towels How many loads of laundry will it take to wash all the oversized beach towels? ** The washing machine can only hold 14 towels and they have 84 towels to wash which means there are 84/14 =<<84/14=6>>6 loads of laundry #### 6 A gallon of whole milk that normally costs $3 is now sold at $2. A box of cereal was sold at a discount of $1. How much will you save via discounts if you buy 3 gallons of whole milk and 5 boxes of cereal? How much is the discount for each gallon of whole milk? ** The discount for each gallon of whole milk is $3 - $2 = $<<3-2=1>>1. How much is the discount for 3 gallons of whole milk? ** So the discount for 3 gallons of whole milk is $1/gallon x 3 gallons = $<<1*3=3>>3. How much is the discount for 5 boxes of cereal? ** The total discount for 5 boxes of cereal is $1/box x 5 boxes = $<<1*5=5>>5. How much will you save via discounts if you buy 3 gallons of whole milk and 5 boxes of cereal? ** You will save $3 + $5 = $<<3+5=8>>8 for 3 gallons of whole milk and 5 boxes of cereal. #### 8 Janice's office is on the third floor, and she has to walk up 3 flights of stairs to get to her office. In a single day, she goes up the three flights of stairs 5 times, down the the three flights of stairs 3 times, and uses the elevator the remainder of the time. How many flights of stairs does Janice walk (up and down) in a single day? How many flights of stairs does Janice walk up in a single day? ** Janice walks up 3 flights of stairs 5 times per day, for a total of 3*5 = <<3*5=15>>15 flights of stairs How many flights of stairs does Janice walk down in a single day? ** Janice walks down 3 flights of stairs 3 times per day, for a total of 3*3 = <<3*3=9>>9 flights of stairs How many flights of stairs does Janice walk in a single day? ** In total, she walks 15+9=<<15+9=24>>24 flights of stairs in a single day #### 24 Fern is checking IDs to get into an R-rated movie. She denied 20% of the 120 kids from Riverside High, 70% of the 90 kids from West Side High, and half the 50 kids from Mountaintop High. How many kids got into the movie? How many kids from Riverside High are rejected? ** First find how many kids from Riverside High are rejected: 20% * 120 kids = <<20*.01*120=24>>24 kids How many kids from West Side High are rejected? ** Then find how many kids from West Side High are rejected: 70% * 90 kids = <<70*.01*90=63>>63 kids How many kids from Mountaintop High are rejected? ** Then find how many kids from Mountaintop High are rejected: 50 kids / 2 = <<50/2=25>>25 kids How many kids are rejected? ** Then add the number of kids from each school to find the total number of kids: 120 kids + 90 kids + 50 kids = <<120+90+50=260>>260 kids How many kids got in? ** Then subtract all the kids who were rejected from the total number of kids to find the number who got in: 260 kids - 24 kids - 63 kids - 25 kids = <<260-24-63-25=148>>148 kids #### 148 Larry spends half an hour twice a day walking and playing with his dog. He also spends a fifth of an hour every day feeding his dog. How many minutes does Larry spend on his dog each day? How many minutes does Larry spend walking his dog? ** Larry spends 30 * 2 = <<30*2=60>>60 minutes per day walking his dog. How many minutes does Larry spend feeding his dog? ** Larry spends 60 / 5 = <<60/5=12>>12 minutes every day feeding his dog. How many minutes does Larry spend on his dog? ** Larry spends 60 + 12 = <<60+12=72>>72 minutes per day on his dog. #### 72 A cleaning company produces two sanitizer sprays. One spray kills 50% of germs, and another spray kills 25% of germs. However, 5% of the germs they kill are the same ones. What percentage of germs would be left after using both sanitizer sprays together? How many germs are left after the first spray? ** After the first spray kills 50% of germs, there will be 100 - 50 = <<100-50=50>>50% left. How many germs are left after the second spray? ** The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = <<25-5=20>>20%. What percentage of germs are left after using both sanitizer sprays together? ** After the second spray kills 20% of the remaining germs, there will be 50 - 20 = <<50-20=30>>30% left. #### 30 Toby is counting goldfish in the local pond. He knows that only 25% of goldfish are at the surface and the rest are too deep below the surface to be able to see. If he counts 15 goldfish, how many are below the surface? How many goldfish are there? ** There are 60 goldfish because 15 / .25 = <<15/.25=60>>60 How many goldfish are below the surface? ** 75% of the fish are below the surface because 100 - 25 = <<100-25=75>>75 How many goldfish are below the surface? ** There are 45 goldfish below the surface because 60 x .75 = <<60*.75=45>>45 #### 45 The owner of a Turkish restaurant wanted to prepare traditional dishes for an upcoming celebration. She ordered ground beef, in four-pound packages, from three different butchers. The following morning, the first butcher delivered 10 packages. A couple of hours later, 7 packages arrived from the second butcher. Finally, the third butcher’s delivery arrived at dusk. If all the ground beef delivered by the three butchers weighed 100 pounds, how many packages did the third butcher deliver? How many pounds did the first butcher deliver? ** Since each package weighed 4 pounds, the first butcher delivered 10 * 4 = <<10*4=40>>40 pounds How many pounds did the second butcher deliver? ** The second butcher's delivery was 7 * 4 = <<7*4=28>>28 pounds How many pounds did the first two butchers deliver? ** The first two butchers therefore delivered 40 + 28 = <<40+28=68>>68 pounds How many pounds did the third butcher deliver? ** Subtracting that weight from the total weight of ground beef gives 100 - 68 = <<100-68=32>>32 pounds How many packages did the third butcher deliver? ** It therefore means the third butcher delivered 32/4 = <<32/4=8>>8 packages. #### 8 James watched 2 episodes of Jeopardy and 2 episodes of Wheel of Fortune.

How many minutes does Wheel of Fortune take? ** Wheel of Fortune is 2*20=<<2*20=40>>40 minutes each. How many minutes did he watch Wheel of Fortune? ** So he watched it for 40*2=<<40*2=80>>80 minutes. How many minutes did he watch TV? ** So he watched 40+80=<<40+80=120>>120 minutes of TV. How many hours did he watch TV? ** That means he watched 120/60=<<120/60=2>>2 hours of TV. #### 2 Richard can clean his room in 22 minutes.
