Phil and Andre decide to order some pizza. They get a small cheese and a large pepperoni. The small pizza has 8 slices, The large has 14 slices. They have both eaten 9 slices already. How many pieces are left per person?

There are 22 pieces of pizza because 14 plus 8 equals

<<14+8=22>>22. They have eaten 18 pieces of pizza because 9 plus 9 equals <<9+9=18>>18. There are 4 pieces of pizza left because 22 minus 18 equals <<22-18=4>>4. There are 2 pieces per person because 4 divided by 2 equals <<4/2=2>>2. #### 2 Tony has a bucket that holds 2 pounds of sand. He has a sandbox out back that is two feet deep, four feet wide, and 5 feet long. A cubic foot of sand weighs 3 pounds. Because it's hot outside, he wants to make sure he stays hydrated, so every 4 trips he takes he drinks 3 ounces of bottled water. A 15 ounce bottle of water costs $2. He has $10 with him. How much change will he have after he buys all the water he needs? The sandbox is 40 cubic feet because 2 x 4 x 5 = <<2*4*5=40>>40 He needs 120 pounds of sand because 40 x 3 = <<40*3=120>>120 He will take 60 trips because 120 / 2 = <<120/2=60>>60 He will need to drink water 15 times because 60 / 4 = <<60/4=15>>15 He will drink 45 ounces of water because 15 x 3 = <<15*3=45>>45 He will need 3 bottles of water because 45 / 15 = <<45/15=3>>3 He will spend $6 on water because 3 x 2 = <<3*2=6>>6 He will have $4 in change because 10 - 6 = <<10-6=4>>4 #### 4 The PTA had saved $400 set aside after a fundraising event. They spent a fourth of the money on school supplies. Then they spent half of what was left on food for the faculty. How much money did they have left? They spent $400/4=$<<400/4=100>>100 on school supplies. They spent $300/2=$<<300/2=150>>150 on food. They had $300-150=$<<300-150=150>>150 left. #### 150 William read 6 books last month and Brad read thrice as many books as William did. This month, in an effort to catch up, Williams read twice as much as Brad, who read 8 books. Who has read more across the two months, and by how much? Last month Brad read thrice 6 books for a total of 3*6 = <<3*6=18>>18 books This month Williams read twice 8 books for a total of 2*8 = <<2*8=16>>16 books Across the 2 months Brad has read 18+8 = <<18+8=26>>26 books Across the 2 months William has read 6+16 = <<6+16=22>>22 books Brad has read 26-22 = <<26-22=4>>4 more books #### 4 Twenty years ago, Shane was 2 times older than Garret is now. If Garret is currently 12, how old is Shane now? Twenty years ago, Shane was 12 * 2 = <<12*2=24>>24 years old Shane is currently 24 + 20 = <<24+20=44>>44 years old #### 44 Traveling from Manhattan to the Bronx, Andrew rides the subway for 10 hours, takes the train and rides for twice as much time as the subway ride, and then bikes the remaining distance for 8 hours. What's the total time he takes to reach the Bronx from Manhattan? The train ride takes Andrew 2*10 = <<2*10=20>>20 hours. Together, the subway ride and the train ride take Andrew 10+20 = <<10+20=30>>30 hours. With an additional bike ride of 8 hours to reach the Bronx, Andrew takes 30+8 = <<30+8=38>>38 hours to travel from Manhattan to the Bronx. #### 38 Each bank teller has 10 rolls of coins. Each roll has 25 coins. How many coins do four bank tellers have in all? Each bank teller has 10 x 25 = <<10*25=250>>250 coins. Thus, four bank tellers have 250 x 4 = <<250*4=1000>>1000 coins. #### 1000 John buys a vacuum cleaner for $250 and a dishwasher for $450. She has a $75 off coupon. How much did he spend? The combined price was 250+450=$<<250+450=700>>700 So he paid 700-75=$<<700-75=625>>625 #### 625 A question and answer forum has 200 members. The average number of answers posted by each member on the forum is three times as many as the number of questions asked. If each user posts an average of 3 questions per hour, calculate the total number of questions and answers posted on the forum by its users in a day. If each user posts an average of 3 questions per hour, the average number of answers posted on the forum is 3 times the number of questions which totals to 3*3 = <<3*3=9>>9 answers per hour. In a day, with 24 hours, the average number of questions asked by each member is 24*3 = <<24*3=72>>72, If there are 200 users of the forum, the total number of questions asked is 200*72 = <<200*72=14400>>14400 questions in a day. At the same time, a member posts an average of 9*24 = <<9*24=216>>216 answers in a day. Since there are 200 members who use the forum, the total number of answers posted in the forum in a day is 200*216 = <<200*216=43200>>43200. In total, the number of questions and answers posted on the forum is 43200+14400 = <<43200+14400=57600>>57600 #### 57600 Mark and his sister Chris both leave their house for school at the same time. Mark travels at the same speed as Chris, who walks 3 miles per hour. After walking 3 miles Mark has to turn around and go home because he forgot his lunch. If the distance from their house to the school is 9 miles, how much longer does Mark spend walking than Chris? First find the total number of miles Mark walks to get his lunch by multiplying the distance he walks back to the house by 2: 3 miles * 2 = <<3*2=6>>6 miles Then find the total distance Mark walks by adding that distance to the distance between the house and the school: 6 miles + 9 miles = <<6+9=15>>15 miles Now divide the total distance Mark walks by his speed to find how many hours he spends walking: 15 miles / 3 miles/hour = <<15/3=5>>5 hours Now divide the total distance Chris walks by her speed to find the total time she spends walking: 9 miles / 3 miles/hour = <<9/3=3>>3 hours Now subtract the time Chris spends walking from the time Mark spends walking to find the difference: 5 hours - 3 hours = <<5-3=2>>2 #### 2
