How much money did Hannah make from selling the cookies? ** Hannah's earnings from the cookies is 40 x $0.8 = $

<<40*0.8=32>>32. How much money did Hannah make from selling the cupcakes? ** Her earnings from the cupcakes is 30 x $2 = $<<30*2=60>>60. How much money did Hannah make in total? ** Her total earnings for the cupcakes and cookies is $32 + $60 = $<<32+60=92>>92. How much did Hannah spend on the measuring spoons? ** The cost of 2 sets of measuring spoons is 2 x $6.5 = $<<2*6.5=13>>13. How much money does Hannah have left? ** So, Hannah has $92 - $13 = $<<92-13=79>>79. #### 79 Anne is 2 times as tall as her sister while Bella is 3 times as tall as Anne. If Anne is 80cm tall, what is the height difference between Bella and Anne's sister? How tall is Anne? ** Anne is 2 times as tall as her sister hence 2*(her sister's height) = 80cm How tall is Anne's sister? ** Her sister's height = 80cm/2 = <<80/2=40>>40cm How tall is Bella? ** Bella is 3 times as tall as Anne hence Bella's height is 3*80 cm = <<3*80=240>>240 cm How tall is the height difference between Bella and Anne's sister? ** The height difference between Bella and Anne's sister = 240-40 = <<240-40=200>>200cm #### 200 Adam goes to a small school, which teaches 80 students in three classes. 40% of the students are in class A, and class B has 21 students fewer than class A. The rest are in class C. How many students are in this class? How many students are in class A? ** In class A, there are 40/100 * 80 = <<40/100*80=32>>32 students. How many students are in class B? ** In class B, the number of students is less by 21, which means class B has 32 - 21 = <<32-21=11>>11 students. How many students are in class C? ** That means 80 - 32 - 11 = <<80-32-11=37>>37 students are in class C. #### 37 Every hour past noon shadows from a building stretch an extra 5 feet, starting at zero at noon. How long are the shadows from the building 6 hours past noon in inches? How long are the shadows from the building 6 hours past noon in inches? ** If the shadows lengthen by 5 feet per hour, this means that in 6 hours the shadows would have lengthened from zero to 5*6=<<5*6=30>>30 feet. How long are the shadows from the building 6 hours past noon in inches? ** Since there are 12 inches in every foot, this means the building's shadow would be 30*12= <<30*12=360>>360 inches in length. #### 360 You can buy 4 apples or 1 watermelon for the same price. You bought 36 fruits evenly split between oranges, apples and watermelons, and the price of 1 orange is $0.50. How much does 1 apple cost if your total bill was $66? How many units of each fruit did I buy? ** If 36 fruits were evenly split between 3 types of fruits, then I bought 36/3 = <<36/3=12>>12 units of each fruit How much do 12 oranges cost? ** If 1 orange costs $0.50 then 12 oranges will cost $0.50 * 12 = $<<0.5*12=6>>6 How much did I spend on the other 2 fruit types? ** If my total bill was $66 and I spent $6 on oranges then I spent $66 - $6 = $<<66-6=60>>60 on the other 2 fruit types. How much does 1 watermelon cost? ** Assuming the price of watermelon is W, and knowing that you can buy 4 apples for the same price and that the price of one apple is A, then 1W=4A How much did we spend? ** If we know we bought 12 watermelons and 12 apples for $60, then we know that $60 = 12W + 12A How much did we spend? ** Knowing that 1W=4A, then we can convert the above to $60 = 12(4A) + 12A How much did we spend? ** $60 = 48A + 12A How much did we spend? ** $60 = <<60=60>>60A How much does one apple cost? ** Then we know the price of one apple (A) is $60/60= $<<60/60=1>>1 #### 1 Jill and her brother Jack are going apple picking. Jill's basket can hold twice as much as Jack's basket when both are full. Jack's basket is full when it has 12 apples, but currently space for 4 more. How many times could Jack's current number of apples fit into Jill's basket? How many apples can Jill's basket hold? ** Since Jill's basket can hold twice as much as Jack's, and Jack's is capable of holding 12 apples in total, this means Jill's basket can hold 12*2=<<12*2=24>>24 apples in total. How many apples does Jack have? ** Since Jack has 4 less than the maximum amount of apples he can fit in his basket, this means Jack has 12-4= <<12-4=8>>8 apples in his basket. How many times could Jack's current number of apples fit into Jill's basket? ** Therefore, Jill's basket can hold 24/8= <<24/8=3>>3 times the amount of apples Jack is currently carrying. #### 3 John plants a plot of 3 trees by 4 trees. Each tree gives 5 apples. He sells each apple for $.5. How much money does he make, in dollars? How many trees does John plant? ** He has 3*4=<<3*4=12>>12 trees How many apples does John plant? ** So he has 12*5=<<12*5=60>>60 apples How much money does John make? ** So he sells the apples for 60*.5=$<<60*.5=30>>30 #### 30 An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month? How much does the restaurant earn on weekdays? ** On weekdays it earns $600/weekday * 5 weekdays = $<<600*5=3000>>3000 How much does the restaurant earn on the weekend? ** During the weekend it earns twice as much each day so it makes ($600 * 2)/weekend day * 2 weekend days = $<<(600*2)*2=2400>>2400 How much does the restaurant earn in total? ** Every week it earns $3000 + $2400 = $<<3000+2400=5400>>5400 How much does the restaurant earn by the end of the month? ** By the end of the month, it earns $5400/week * 4 weeks = $21600 #### 21600 Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples. Barry can reach apples that are 5 feet high. Larry is 5 feet tall, but his shoulder height is 20% less than his full height. If Barry stands on Larry's shoulders, how high can they reach? How tall is Larry's shoulder? ** Larry's shoulder height is 20% less than 5 feet, or 0.2*5 =<<20*.01*5=1>>1 foot less than 5 feet. How tall is Larry's shoulder? ** One foot less than 5 feet is 5-1=<<5-1=4>>4 feet. How high can they reach? ** If Barry stands on Larry's shoulders, they can reach 4+5=<<4+5=9>>9 feet. #### 9 Johns goes to the gym 3 times a week. He spends 1 hour each day lifting weight. Additionally, he also spends a third of his weightlifting time warming up and doing cardio each day. How many hours does he spend at the gym a week? How many minutes does he spend warming up? ** He spends 60/3=<<60/3=20>>20 minutes warming up How many minutes does he spend at the gym each day? ** So he spends 60+20=<<60+20=80>>80 minutes at the gym per day How many minutes does he spend at the gym in a week? ** That means he spends 80*3=<<80*3=240>>240 minutes at the gym How many hours does he spend at the gym a week? ** So he spends 240/60=<<240/60=4>>4 hours at the gym a week #### 4
