While bird watching, Gabrielle saw 5 robins, 4 cardinals, and 3 blue jays. Chase saw 2 robins, 3 blue jays, and 5 cardinals. How many more birds, in percentage, did Gabrielle saw than Chase?

Gabrielle saw 5 + 4 + 3 =

<<5+4+3=12>>12 birds. Chase saw 2 + 3 + 5 = <<2+3+5=10>>10 birds. So, Gabrielle saw 12 - 10 = <<12-10=2>>2 more birds than Chase. Therefore, Gabrielle saw 2/10 x 100% = 20% more birds than Chase. #### 20 Stephanie is moving into a new apartment. She needs to figure out how many pieces of silverware she should purchase. She needs spoons, butter knives, steak knives, and forks. For herself she figures 5 of each would be sufficient. But in case she has guests, she wants to have 10 extra pieces of each type. Then she realizes that if everything is clean at the same time, that she will have too many of everything and not enough room to fit them in her kitchen silverware drawer. So she decides to purchase 4 fewer spoons, 4 fewer butter knives, 5 fewer steak knives, and 3 fewer forks. How many pieces total of all the silverware is Stephanie going to buy? Stephanie wants to get 5 each of each type of silverware for herself. 5 spoons + 5 butter knives + 5 steak knives + 5 forks = <<5+5+5+5=20>>20 pieces of silverware She wants 10 extra of each type for guests, 10 x 4 = <<10*4=40>>40 She decides to purchase less of each type. She was originally purchasing 15 of each type. 15 spoons - 4 less spoons = 11 spoons. 15 butter knives - 4 less = 11. 15 steak knives - 5 = 10. 15 forks - 3 less forks = 12. Stephanie is going to purchase 11 spoons, 11 butter knives, 10 steak knives, and 12 forks. 11 + 11 + 10 + 12 = <<11+11+10+12=44>>44. Stephanie is going to purchase 44 pieces of silverware. #### 44 A newspaper subscription costs $10/month. If you purchase an annual subscription you obtain a 20% discount on your total bill. How much do you end up paying if you go with the annual subscription? A year has 12 months. If 1 month costs $10, then a year will cost $12 * 10 = $<<12*10=120>>120 per year without an annual subscription If the annual subscription has a 20% discount then you would pay $120 * (1-20%) = $<<120*(1-20*.01)=96>>96 for the annual subscription #### 96 A road has four lanes, and in each lane, the number of cars is twice as many as the number of trucks in all the lanes. If there are 60 trucks in each lane, calculate the total number of vehicles in all the lanes? If the road has four lanes and 60 trucks in each lane, the total number of trucks in all the lanes is 60*4 = <<4*60=240>>240. Since in each lane the number of cars is twice as many as the number of trucks in all the lanes, there are 2*240=480 cars in each lane. The total number of cars in all the lanes is 480*4 = <<480*4=1920>>1920 In all the lanes, the total number of vehicles is 240 trucks+1920 cars = <<240+1920=2160>>2160 #### 2160 In Zeoland the fine for speeding is $16 for each mile per hour the driver is traveling over the posted speed limit. In Zeoland, Jed was fined $256 for speeding on a road with a posted speed limit of 50 mph. Jed was fined for traveling at what speed in miles per hour? First find how much Jed was above the speed limit: $256 fine / $16 for each mile per hour over = <<256/16=16>>16 miles per hour over. Since the speed limit is 50 mph, this means Jed was driving 50 + 16 = <<50+16=66>>66 mph. #### 66 Danny helps his friends carpool to work. He has to drive 8 miles to the first friend's house, half that distance to the second friend's house, then 3 times the total distance driven so far to get to work. How many miles does Danny drive between the second friend's house and work? First find the distance to the second friend's house by halving the distance to the first friend's house: 8 miles / 2 = <<8/2=4>>4 miles Then add that amount to the distance to the first friend's house: 4 miles + 8 miles = <<4+8=12>>12 miles Then triple that number to find the distance from the second friend's house to work: 12 miles * 3 = <<12*3=36>>36 miles #### 36 On the last night that roller skate rink was open, 40 people showed up to roller skate one last time. When all 40 people skated at one time, how many wheels were on the floor? 40 people were roller skating and they all had 2 feet which means there were 40*2 = <<40*2=80>>80 feet Each foot needs a roller skate and each roller skate has 4 wheels so 80*4 = <<80*4=320>>320 wheels when everyone skated #### 320 There are six peregrine falcons and 40 pigeons nesting in Malcolm's skyscraper. Each pigeon has 6 chicks. If the peregrines eat 30% of the pigeons, how many pigeons are left? First find the total number of chicks: 40 pigeons * 6 chicks/pigeon = <<40*6=240>>240 chicks Then add that to the number of adult pigeons to find the total number of pigeons: 240 chicks + 40 pigeons = <<240+40=280>>280 pigeons Then multiply that number by 30% to find the number of pigeons that were eaten: 280 pigeons * 30% = <<280*30*.01=84>>84 pigeons Then subtract that number from the total number of pigeons to find the number that are left: 280 pigeons - 84 pigeons = <<280-84=196>>196 pigeons #### 196 When Erick went to the market to sell his fruits, he realized that the price of lemons had risen by $4 for each lemon. The price of grapes had also increased by half the price that the price of lemon increased by per grape. If he had planned to sell the lemons at $8 and the grapes at $7, and he had 80 lemons and 140 grapes in his basket, how much money did he collect from selling the fruits at the new prices? The new price for each lemon after increasing by $4 is $8+$4 = $<<8+4=12>>12 For the 80 lemons, Erick received $12*80 = $<<12*80=960>>960 The price of each grape increased by 1/2*$4 = $<<1/2*4=2>>2 The new price at which Erick sold his grapes is $7+$2 = $<<7+2=9>>9 For the 140 grapes, Erick collected 140*$9 = $<<140*9=1260>>1260 From the sale of all of his fruits, Erick received $1260+$960 = $<<1260+960=2220>>2220 #### 2220 Lloyd is building a house of cards. He owns 16 decks of cards that have 52 cards each. If each layer of his house of cards has the same exact number of cards, how many cards are there per layer if his house is 32 layers tall? He has 832 cards because 16 x 52 = <<16*52=832>>832 Each layer is 26 cards because 832 / 32 = <<832/32=26>>26 #### 26
