Nala found 5 seashells at the beach. The next day, she found another 7, and the following day, she found twice the number she got from the first two days. How many seashells does Nala have?

How many seashells did Nala find on the first and second days? ** On the first and second days, Nala found 5 + 7 =

<<5+7=12>>12 seashells. How many seashells did Nala find on the third day? ** On the third day, she found 12 x 2 = <<12*2=24>>24 seashells. How many seashells does Nala have? ** Altogether, she found 12 + 24 = <<12+24=36>>36 seashells. #### 36 The age of a lioness in a park is twice the age of a hyena in the same park. The lioness is 12 years old. If the babies of the two animals are half the age of their mothers, calculate the sum of the age of the babies in five years. How old is the hyena? ** If the lioness is 12 years old, the hyena, half her age, is 12/2 = <<12/2=6>>6 years old. How old is the baby of the lioness? ** The baby of the lioness is 12/2 = <<12/2=6>>6 years old, half the mother's age. How old will the lioness's cub be in five years? ** Five years from now, the age of the lioness's cub will be 6+5 = <<6+5=11>>11 How old is the baby of the hyena? ** The baby of the hyena is 6/2 = <<6/2=3>>3 years old, which is half the mother's age. How old will the hyena's baby be in five years? ** The hyena's baby will be 3+5 = 8 years old in five years. How old will the babies be in five years? ** Together, the total age of the babies will be 8+11 = <<8+11=19>>19 years in five years. #### 19 Jame has 60 bars of gold. He uses 10% of them to pay for tax and then loses half of what is left in divorce. How many gold bars does he have left? How many bars does Jame lose to taxes? ** He loses 60*.1=<<60*.1=6>>6 bars to taxes How many bars does Jame have after taxes? ** That means he has 60-6=<<60-6=54>>54 bars after taxes How many bars does Jame have after the divorce? ** So he has 54/2=<<54/2=27>>27 bars after the divorce #### 27 Each turtle lays a clutch of 20 eggs. If 40% of the eggs successfully hatch, how many hatchlings do 6 turtles produce? How many eggs does each turtle successfully hatch? ** First find the number of eggs that each turtle successfully hatches: 20 eggs * 40% = <<20*40*.01=8>>8 eggs How many eggs does each turtle successfully hatch? ** Then multiply the number of eggs per turtle by the number of turtles to find the total number of eggs: 8 eggs/turtle * 6 turtles = <<8*6=48>>48 turtles #### 48 Isabelle gets a job so she can save enough money to go to a concert with her two brothers. Her ticket costs $20. Her brothers both get the children’s discount, and each of their tickets cost $10. Her brothers have saved $5 between the two of them and Isabelle has saved $5. If her job pays $3 per week, how many weeks must she work to afford the tickets? How much will the tickets cost? ** The tickets for both of her brothers will cost her $10 * 2 = $<<10*2=20>>20. How much will the tickets cost? ** To buy tickets for all of them, it will cost Isabelle $20 + $20 = $<<20+20=40>>40. How much have they saved? ** Between all of them, they have saved a total of $5 + $5 = $<<5+5=10>>10. How much does she need to earn? ** Since they have already saved $10, she needs to earn an additional $40 - $10 = $<<30=30>>30 to afford the tickets. How many weeks must she work? ** Since she makes $3 per week, it will take her $30 / ($3/week) = <<30/(3)=10>>10 weeks to save enough money for all of the tickets. #### 10 Darren bought 4 boxes of crackers. Each box contained 24 crackers. If Calvin bought one box less than twice as many boxes of crackers as Darren, how many crackers did they buy altogether? How many crackers did Darren buy? ** If Darren bought 4 boxes of crackers, each containing 24 crackers, the total number of crackers that Darren bought is 24*4=<<24*4=96>>96 How many boxes of crackers did Calvin buy? ** Twice as many boxes of crackers as Darren bought is 2*4=<<2*4=8>>8 How many boxes of crackers did Calvin buy? ** If Calvin bought one box less than twice as many boxes of crackers as Darren, then Calvin bought 8-1=<<8-1=7>>7 boxes of crackers. How many crackers did Calvin buy? ** The total number of crackers that Calvin bought is 7*24=<<7*24=168>>168 How many crackers did Darren and Calvin buy altogether? ** Together, Darren and Clavin bought 168+96=<<168+96=264>>264 crackers. #### 264 Lyssa and Precious took an English proficiency exam. Lyssa answered 20% of the items incorrectly. Precious got 12 mistakes. How many more correct answers did Lyssa get than precious if there were 75 items in the exam? How many mistakes did Lyssa get? ** Lyssa got 75 x 20/100 = <<75*20/100=15>>15 mistakes. How many correct answers did Lyssa get? ** Lyssa's score is 75 - 15 = <<75-15=60>>60. How many correct answers did Precious get? ** The score of Precious is 75 - 12 = <<75-12=63>>63. How many more correct answers did Lyssa get than Precious? ** Thus, Lyssa got 63 - 60 = <<63-60=3>>3 more correct answers than Precious. #### 3 Adlai has 2 dogs and 1 chicken. How many animal legs are there in all? How many legs do 2 dogs have? ** Since dogs have 4 legs, then 2 dogs have a total of 2 x 4 = <<2*4=8>>8 legs. How many legs are there in all? ** So, there are 8 dog legs + 2 chicken legs = <<8+2=10>>10 legs in all. #### 10 One US cup equals 250ml. Brian is making lasagna for himself, his wife, his two kids, his parents, and his wife's parents. The recipe requires 1/2 a cup of milk per serving. How many 1L cartons of milk does Brian need to buy if each person is expected to eat 2 servings? How many people are eating? ** There will be a total of (1) Brian + (1) Brian's wife + (2) two kids + (2) Brian's parents + (2) Brian's in-laws = 1+1+2+2+2= <<1+1+2+2+2=8>>8 people eating How many servings will be eaten? ** If 1 person eats 2 serving of lasagna then 8 people will eat 8 * 2 = <<8*2=16>>16 servings How many cups of milk are needed? ** If each serving requires 1/2 cup of milk then 16 servings require 16 * 1/2 cups = <<16*1/2=8>>8 cups of milk How many ml of milk are needed? ** If one cup of milk equals 250 ml, then 8 cups of milk equal 8 * 250 = <<8*250=2000>>2000 ml of milk How many 1L cartons of milk does Brian need to buy? ** 1L carton of milk equals 1000ml of milk, therefore Brian needs 2000/1000 = <<2000/1000=2>>2 cartons of 1L milk #### 2 The teacher brings in 14 mini-cupcakes and 12 donut holes for the class. There are 13 students in the class. If each student gets the exact same amount, how many desserts does each student get? How many desserts are there? ** There are 26 total desserts because 14 plus 12 equals <<14+12=26>>26. How many desserts does each student get? ** Each student gets 2 desserts because 26 divided by 13 equals <<26/13=2>>2. #### 2
