A charity is delivering chicken and rice dinners to a shelter for the hungry. They have a hundred plates to deliver. The rice cost ten cents a plate and the chicken cost forty cents a plate. How many dollars did the charity spend on the food for the dinners?

Each chicken and rice plate cost 10 + 40 =

<<10+40=50>>50 cents. The charity spent 50 * 100 = <<50*100=5000>>5000 cents for the dinners. There are 100 cents in a dollar, so the charity spent 5000 / 100 = $<<5000/100=50>>50 for the dinners. #### 50 A public official wants to donate 5 new soccer balls per each class in two schools. Each school has 4 elementary school classes and 5 middle school classes. How many soccer balls would the public official donate in all? Each school has 4 + 5 = <<4+5=9>>9 classes. So, there are a total of 9 x 2 = <<9*2=18>>18 classes for the 2 schools. Therefore, the public official donates a total of 18 x 5 = <<18*5=90>>90 soccer balls. #### 90 Hooper Bay has twice as many pounds of lobster than the two other harbors combined. If the other two harbors have 80 pounds of lobster each, how many pounds of lobster are the three harbors holding? Since the other two harbors have 80 pounds of lobsters each, they have a total of 80+80= <<80+80=160>>160 pounds of lobster. Since Hooper Bay has two times more lobsters than the other two harbors combined, it has 2*160 = <<2*160=320>>320 pounds of lobster. In total, the three harbors have 320+160 = <<320+160=480>>480 pounds of lobster. #### 480 James opens up a flower shop. He needs to pay rent of $1200 a week with an additional 20% of rent to pay for utilities and he has 2 employees per shift with the store open 16 hours a day for 5 days a week. If he pays each employee $12.50 an hour, what are his weekly expenses to run the store? He is open 16*5=<<16*5=80>>80 hours a week So he pays each of his employees 12.5*80=$<<12.5*80=1000>>1000 per week Since there are two employees, he pays them in total 2 * $1000 = $<<2*1000=2000>>2000 per week. The utilities cost 1200*.2=$<<1200*.2=240>>240 So his total cost per week is 1200+2000+240=$<<1200+2000+240=3440>>3440 #### 3440 Tom bought 10 packages of miniature racing cars. Each package contains five cars. He gave each of his two nephews 1/5 of the cars. How many miniature racing cars are left with Tom? Tom had 10 x 5 = <<10*5=50>>50 miniature racing cars. Tom gave 50 x 1/5 = <<50*1/5=10>>10 miniature racing cars to each of his two nephews. So, he gave a total of 10 x 2 = <<10*2=20>>20 cars to his two nephews. Therefore, Tom is left with 50 - 20 = <<50-20=30>>30 miniature racing cars. #### 30 Kimiko is retiling her kitchen floor. Each tile is 6 square inches. If her kitchen is 48 inches by 72 inches, how many tiles does Kimiko need to buy? First figure out how many tiles are in one row by dividing the kitchen's width by each tile's width: 48 inches / 6 inches/tile = <<48/6=8>>8 tiles in one row Then figure out how many rows of tiles there are by dividing the kitchen's height by each tile's height: 72 inches / 6 inches/tile = <<72/6=12>>12 rows of tiles Then multiply the number of rows by the number of tiles per row to find the total number of tiles Kimiko needs to buy: 8 tiles/row * 12 rows = <<8*12=96>>96 tiles #### 96 If Buzz bought a pizza with 78 slices at a restaurant and then decided to share it with the waiter in the ratio of 5:8, with Buzz's ratio being 5, what's twenty less the number of slices of pizza that the waiter ate? The total ratio representing the slices of pizza that Buzz bought is 5+8=<<5+8=13>>13 If he shared the slices of pizza with the waiter, the waiter received a fraction of 8/13 of the total number of slices, which totals 8/13 * 78 = <<8/13*78=48>>48 slices Twenty less the number of slices of pizza that the waiter ate is 48-20 = <<48-20=28>>28 #### 28 Mitchell is trying to chew as many pieces of gum at once as he can. He has 8 packets of gum, There are 7 pieces in each. If he chews all the gum except for 2 pieces, how many pieces does he chew at once? The packets have 56 pieces in total because 8 x 7 = <<8*7=56>>56 He chews 54 pieces because 56 -2 = <<56-2=54>>54 #### 54 Tim decides to get animals for his zoo. He buys 3 goats for $400 each. He gets twice as many llamas which cost 50% more each. How much did he spend? The goats cost 3*400=$<<3*400=1200>>1200 He buys 3*2=<<3*2=6>>6 llamas Each llama cost 400*1.5=$<<400*1.5=600>>600 So he spends 600*6=$<<600*6=3600>>3600 on llamas. So the total cost was 1200+3600=$<<1200+3600=4800>>4800 #### 4800 Toby has two rectangles of cloth. The first is 4 inches wide and 5 inches tall. The second is 3 inches wide and 6 inches tall. How many more square inches is the area of the first compared to the second? The first has an area of 20 square inches because (4 x 5) = <<4*5=20>>20. The second has an area of 18 square inches because (3 x 6) = <<(3*6)=18>>18. The difference in area is 20-18=<<20-18=2>>2 square inches. #### 2
