Ann, Bill, Cate, and Dale each buy personal pan pizzas cut into 4 pieces. If Bill and Dale eat 50% of their pizzas and Ann and Cate eat 75% of the pizzas, how many pizza pieces are left uneaten?

In total, there are 4 x 4 =

<<4*4=16>>16 pizza pieces. Bill and Dale eat 2 x 4 x 50% = <<2*4*50*.01=4>>4 pieces. Ann and Cate eat 2 x 4 x 75% = <<2*4*75*.01=6>>6 pieces. The four of them eat 4 + 6 = <<4+6=10>>10 pieces. There are 16 - 10 = <<16-10=6>>6 pizza pieces uneaten. #### 6 Noah is a painter. He paints pictures and sells them at the park. He charges $60 for a large painting and $30 for a small painting. Last month he sold eight large paintings and four small paintings. If he sold twice as much this month, how much is his sales for this month? Noah earned $60/large painting x 8 large paintings = $<<60*8=480>>480 for the large paintings. He also earned $30/small painting x 4 small paintings = $<<30*4=120>>120 for the small paintings. His total sales last month were $480 + $120 = $<<480+120=600>>600. So, his sales this month are $600 x 2 = $<<600*2=1200>>1200. #### 1200 A car is driving through a tunnel with many turns. After a while, the car must travel through a ring that requires a total of 4 right-hand turns. After the 1st turn, it travels 5 meters. After the 2nd turn, it travels 8 meters. After the 3rd turn, it travels a little further and at the 4th turn, it immediately exits the tunnel. If the car has driven a total of 23 meters around the ring, how far did it have to travel after the 3rd turn? From the details given, the car has traveled 5 meters at the 1st turn + 8 meters after the 2nd turn + 0 meters after the 4th turn = <<5+8+0=13>>13 meters around the ring. It must therefore have driven 23 total meters – 13 calculated meters = 10 meters after the 3rd turn. #### 10 To make pizza, together with other ingredients, Kimber needs 10 cups of water, 16 cups of flour, and 1/2 times as many teaspoons of salt as the number of cups of flour. Calculate the combined total number of cups of water, flour, and teaspoons of salt that she needs to make the pizza. To make the pizza, Kimber half as many teaspoons of salt as the number of cups of flour, meaning she needs 1/2*16 = <<16*1/2=8>>8 teaspoons of salt. The total number of cups of flour and teaspoons of salt she needs is 8+16 = <<8+16=24>>24 She also needs 10 cups of water, which means the total number of cups of water and flour and teaspoons of salt she needs is 24+10 = <<24+10=34>>34 #### 34 Mr. Sam shared a certain amount of money between his two sons, Ken and Tony. If Ken got $1750, and Tony got twice as much as Ken, how much was the money shared? Tony got twice $1750 which is 2*$1750 = $<<2*1750=3500>>3500 The total amount shared was $1750+$3500 = $<<1750+3500=5250>>5250 #### 5250 Mr. Sanchez found out that 40% of his Grade 5 students got a final grade below B. How many of his students got a final grade of B and above if he has 60 students in Grade 5? Since 40% of his students got below B, 100% - 40% = 60% of Mr. Sanchez's students got B and above. Thus, 60 x 60/100 = <<60*60/100=36>>36 students got B and above in their final grade. #### 36 Lisa, Jack, and Tommy earned $60 from washing cars all week. However, half of the $60 was earned by Lisa. Tommy earned half of what Lisa earned. How much more money did Lisa earn than Tommy? Lisa earned $60 * 1/2 = $<<60*1/2=30>>30. Tommy earned $30 * 1/2 = $<<30*1/2=15>>15. Lisa earned $30 - $15 = $<<30-15=15>>15 more than Tommy. #### 15 Five friends eat at a fast-food chain and order the following: 5 pieces of hamburger that cost $3 each; 4 sets of French fries that cost $1.20; 5 cups of soda that cost $0.5 each; and 1 platter of spaghetti that cost $2.7. How much will each of them pay if they will split the bill equally? The cost of 5 pieces of hamburger is $3 x 5 = $<<3*5=15>>15. The cost of 4 sets of French fries is $1.20 x 4 = $<<1.20*4=4.80>>4.80. The cost of 5 cups of soda is $0.5 x 5 = $<<0.5*5=2.50>>2.50. So their total bill is $15 + $4.80 + $2.50 +$2.7 = $<<15+4.8+2.5+2.7=25>>25. Hence, each of the five friends will contribute $25/5 = $<<25/5=5>>5. #### 5 Artemis is making tea for a party. She knows her mom drinks an 8-ounce cup of tea and uses one ounce of tea. She will use this same ratio for the party. The party has 12 people there and each of them wants a 6-ounce cup of tea. How many ounces of tea does she need? She is making 72 ounces of water because 12 x 6 = <<12*6=72>>72 She needs 9 ounces of tea because 72 / 8 = <<72/8=9>>9 #### 9 Anna goes trick-or-treating in a subdivision where she gets 14 pieces of candy per house. Her brother Billy goes trick-or-tricking in a neighboring subdivision where he gets 11 pieces of candy per house. If the first subdivision has 60 houses and the second subdivision has 75 houses, how many more pieces of candy does Anna get? First find the total number of pieces of candy Anna gets: 14 pieces/house * 60 houses = 840 pieces Then find the total number of pieces of candy Billy gets: 11 pieces/house * 75 houses = <<11*75=825>>825 pieces Then subtract the number of pieces Billy gets from the number Anna gets to find the difference: 840 pieces - 825 pieces = <<840-825=15>>15 pieces #### 15
