Marissa's sunflower is 21 inches taller than her little sister. If her sister is 4 feet 3 inches tall, how tall is Marissa's sunflower in feet?

Since 1 foot is equal to 12 inches, then 4 feet is equal to 4 x 12 =

<<4*12=48>>48 inches. So, Marissa's sister is 48 + 3 = <<48+3=51>>51 inches tall. The sunflower is 51 + 21 = <<51+21=72>>72 inches tall. Therefore, the sunflower is 72/12 = <<72/12=6>>6 feet tall. #### 6 Normally Ann can frost a cake in 5 minutes. However, today she has a sprained wrist and it takes her 8 minutes to frost a cake. How much longer would it take her to frost 10 cakes with her sprained wrist? Normally, it would take her 5*10=<<5*10=50>>50 minutes With her sprained wrist it will take her 8*10=<<8*10=80>>80 minutes 80-50=<<80-50=30>>30 more minutes #### 30 Frank wants to buy a new lamp for his bedroom. The cost of the cheapest lamp is $20, and the most expensive in the store is 3 times more expensive. How much money would Frank have remaining, if he currently has $90, and he buys the most expensive lamp available? The most expensive lamp cost 20 * 3 = $<<20*3=60>>60. So if Frank would pay for that lamp, he would leave himself with 90 - 60 = $<<90-60=30>>30. #### 30 Angus has $20 worth of tokens less than Elsa has. If Elsa has 60 tokens and each token is worth $4, how many tokens does Angus have? If each token is worth $4, then $20 worth of tokens is $20/$4 = <<20/4=5>>5 tokens Angus has 5 tokens less than Elsa who has 60 so Angus has 60-5 = <<60-5=55>>55 tokens #### 55 The price of an iPhone fell 10% in a particular month and another 20% in the second month. If the initial price was $1000, calculate the price after the second month. In the first month, the price of the iPhone fell by 10/100*$1000=$<<10/100*1000=100>>100 The new price after the first month is $1000-$100 = $<<1000-100=900>>900 In the second month, the price fell 20% further by 20/100*$900 = $<<20/100*900=180>>180 The new price after the second month is $900-$180 = $<<900-180=720>>720 #### 720 Mark constructs a cube of pure gold. The cube is 6 cm on each side. The density of gold is 19 grams per cubic centimeter. He buys the gold for $60 per gram. He sells it for 1.5 times its gold value. What was the profit? The cube is 6*6*6=<<6*6*6=216>>216 cubic cm So it has a mass of 216*19=<<216*19=4104>>4104 grams So it uses 60*4104=$<<60*4104=246240>>246240 That means he sells it for 246240*1.5=$<<246240*1.5=369360>>369360 So he has a profit of 369360-246240=$<<369360-246240=123120>>123,120 #### 123120 Martha is grinding a spice paste. She adds 3 tablespoons of ginger, 1 teaspoon of cardamom, 1 teaspoon of mustard, 2 tablespoons of garlic, and four times as much chile powder as mustard. What percentage of the spice paste is ginger, rounded to the nearest integer? (Remember there are three teaspoons per tablespoon.) First convert the ginger to teaspoons: 3 tablespoons * 3 teaspoons/tablespoon = <<3*3=9>>9 teaspoons Then convert the garlic to teaspoons: 2 tablespoons * 3 teaspoons/tablespoon = <<2*3=6>>6 teaspoons Then find how much chile powder there is: 1 teaspoon * 4 = <<1*4=4>>4 teaspoons Then add up the amount of each spice to find the total amount: 9 teaspoons + 6 teaspoons + 4 teaspoons + 1 teaspoons + 1 teaspoon = <<9+6+4+1+1=21>>21 teaspoons Then divide the amount of ginger by the total amount of spice paste and multiply by 100% to find the percentage of the spice paste that's ginger: 9 teaspoons / 21 teaspoons * 100% = 42.857, which rounds down to 43% #### 43 Jed collects stamp cards. Every week, he gets 6 cards. But every two weeks, he gives 2 cards to his friends. If Jed started with 20 cards, after how many weeks will he have a total of 40 cards? In the first week, Jed has 20 + 6 = <<20+6=26>>26 cards. In the second week, he has 26 + 6 = <<26+6=32>>32 cards. But he is left with 32 - 2 = <<32-2=30>>30 cards on the 2nd week after giving 2 cards to his friend. Then Jed has 30 + 6 = <<30+6=36>>36 cards on the 3rd week. He has 36 + 6 = <<36+6=42>>42 cards on the 4th week. After giving his friend 2 cards, he is then left with 42 - 2 = <<42-2=40>>40 cards on the 4th week. Hence, Jed will have a total of 40 cards in 4 weeks. #### 4 Reagan's school has a fish tank with a total of 280 fish of two types, koi fish and goldfish. Over the next 3 weeks, the school added 2 koi fish and 5 goldfish per day. If the tank had 200 goldfish at the end of the three weeks, what's the total number of koi fish in the tank after the three weeks? The total number of days in 3 weeks is 3 * 7 = <<3*7=21>>21 days. If 2 koi fish are added every day, the total after 21 days is 21 * 2 = <<21*2=42>>42 koi fish. if 5 goldfish are added every day, the total after 21 days is 5 * 21 = <<5*21=105>>105 goldfish. The total number of fish in the tank after 3 weeks is 280 + 42 + 105 = <<280+42+105=427>>427 fish. If there were a total of 200 goldfish in the tank after 3 weeks, then the number of koi in the tank is 427 - 200 = 227 koi fish. #### 227 Hillary always buys the Wednesday, Thursday and Friday editions of the local newspaper for $0.50 each. On Sunday, she spends $2.00 to get that copy. How much does she spend on the newspaper over 8 weeks? She buys Wednesday, Thursday and Friday's paper for $0.50 each so that's 3*.50 = $<<3*.50=1.50>>1.50 She spends $1.50 for the weekday papers and $2.00 for the Sunday paper for a total of 1.5+2 = $<<1.5+2=3.50>>3.50 a week Over 8 weeks she spends 8*3.5 = $<<8*3.5=28.00>>28.00 #### 28
