Gracie was 7 inches shorter than Grayson. Grayson was 2 inches taller than Griffin. Griffin is 61 inches tall. How many inches tall is Gracie?

Grayson = 61 + 2 =

<<61+2=63>>63 inches Gracie = 63 - 7 = <<63-7=56>>56 inches Gracie is 56 inches tall. #### 56 3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with. The number of ripe mangoes from the tree is 3/5*400 = <<3/5*400=240>>240 If Lindsay eats 60% of the ripe mangoes, she eats 60/100*240 = <<60/100*240=144>>144 mangoes. The total number of ripe mangoes remaining is 240-144 =<<240-144=96>>96 #### 96 Harris feeds his dog 1 large organic carrot over the course of 1 day. There are 5 carrots in a 1 pound bag and each bag costs $2.00. In one year, how much will Harris spend on carrots? His dog gets 1 carrot a day and there are 365 days in a year, so his dog eats 1*365 = <<1*365=365>>365 carrots There are 5 carrots per bag and he will need 365 carrots, so that's 365/5 = 73 bags of carrots The bags cost $2.00 and he will need 73 bags so that's $2*73 = $<<2*73=146.00>>146.00 worth of organic carrots #### 146 Ping pong balls sell for $.10 each. Johnny buys 10000 for a prank. He gets a 30% discount for buying in such large bulk. How much does he pay? The ping pong balls cost 10000*.10=$<<10000*.10=1000>>1000 So the discount is 1000*.30=$<<1000*.30=300>>300 So he pays 1000-300=$<<1000-300=700>>700. #### 700 A parking garage near Nora's house is 4 stories tall. There are 100 spots per level. There are 58 open parking spots on the first level. There are 2 more open parking spots on the second level than on the first level, and there are 5 more open parking spots on the third level than on the second level. There are 31 open parking spots on the fourth level. How many full parking spots are there in all? There are 4 levels * 100 spots = <<4*100=400>>400 possible parking spots. The second level has 58 open spots + 2 = <<58+2=60>>60 open spots. The third level has 60 open spots + 5 = <<60+5=65>>65 open spots. Total open spots are 58 + 60 + 65 + 31 = <<58+60+65+31=214>>214 open spots. If there are 400 possible spots – 214 open spots = <<400-214=186>>186 full spots. #### 186 Andy is a lawyer who's working on two lawsuits. The first lawsuit has a 30% chance of paying out $5,000,000 upon a win and $0 if he loses it. The second lawsuit has a 50% chance of paying out $1,000,000 if Andy loses and a 50% chance of paying out $2,000,000 if he wins. Expressed as a percentage, how much more likely is it that Andy loses both lawsuits compared to winning both of them? First find the probability that Andy will lose the first lawsuit: 100% - 30% = 70% Then multiply that probability by the probability he loses the second lawsuit: 70% * 50% = 35% Then multiply the probabilities of Andy winning each lawsuit to find the probability he wins them both: 30% * 50% = 15% Then subtract the probability Andy wins both lawsuits from the probability he loses both lawsuits to find the difference: 35% - 15% = 20% #### 20 John needs to take 2 pills a day. One pill costs $1.5. The insurance covers 40% of the cost. How much does he pay in a 30-day month? It cost 2*1.5=$<<2*1.5=3>>3 a day. So it cost 3*30=$<<3*30=90>>90 per day. Insurance covers 90*.4=$<<90*.4=36>>36. So he pays 90-36=$<<90-36=54>>54 a month. #### 54 Mr. Caiden wants to do repairs to his house and requires 300 feet of metal roofing to do this. If each foot of roofing costs $8, and the supplier of the metal roofing brings in 250 feet of metal roofing for free, how much money is Mr. Caiden required to pay for the remaining metal roofing? The supplier brought 300 ft - 250 ft = <<300-250=50>>50 fewer feet of metal roofing. Therefore the total amount of money Mr. Caiden has to pay for the remaining metal roofings is 50 feet * $8/foot = $<<50*8=400>>400 #### 400 Belinda can throw a ball at a speed of 20 feet/second. If the ball flies for 8 seconds before hitting the ground, and Belinda's border collie can run 5 feet/second, how many seconds will it take the border collie to catch up to the ball? First find the total distance the ball flies: 20 feet/second * 8 seconds = <<20*8=160>>160 feet Then divide that distance by the dog's speed to find how long it takes the dog to catch up to the ball: 160 feet / 5 feet/second = <<160/5=32>>32 seconds #### 32 Bart buys $10 of notepads for $1.25 each. They have 60 pages each. How many pages did he buy? He buys 10/1.25=<<10/1.25=8>>8 notepads That means he buys 8*60=<<8*60=480>>480 pages #### 480
