Melanie is making meatballs for dinner. The recipe calls for breadcrumbs. To make the breadcrumbs Melanie is going to tear 2 slices of bread into smaller pieces and then add them to a blender to grind them into fine crumbs. First she tears the bread slices each in half, then tears those halves in half. How many bread pieces is Melanie going to put into the blender?

How many halves does Melanie start with? ** Melanie starts with 1 slice of bread that she tears in half, making 2 halves.

How many pieces does Melanie start with? ** She takes both of those halves and tears them each in half, 2 halves x 2 more halves in half =

<<2*2=4>>4 pieces per slice of bread. How many pieces is Melanie going to put into the blender? ** Melanie is using 2 slices of bread x 4 pieces each = <<2*4=8>>8 pieces overall to add to the blender. #### 8 Robi Ney wants to fill a 120-liter tub. He is amused by letting the water run for 1 minute, then closing the water supply for 1 minute, and so on alternating opening and closing the water supply. But the cap at the bottom of the tub is not very airtight and lets 1 liter of water escape per minute. The flow rate of the tap is 12 liters per minute. How long does it take to fill the tub in minutes? How many liters of water flow into the bathtub in 2 minutes? ** In 2 minutes, 12 liters of water flow into the bathtub and 2 liters (2 minutes x 1 liter/minute ) escape. How many liters of water flow into the bathtub in 2 minutes? ** This will leave 12 – 2 = <<12-2=10>>10 liters of water every two minutes How many liters of water flow into the bathtub in 2 minutes? ** We can divide the number of liters by the number of minutes to find the average flow per minute, which is 10 / 2 = <<10/2=5>>5 liters per minute How long does it take to fill the tub in minutes? ** To fill the tub, it will take 120 liters / 5 liters/min = <<120/5=24>>24 min #### 24 There are 3 meatballs on each spaghetti plate. If Theresa's 3 sons each eat two-thirds of the meatballs on their respective plates, how many meatballs are still left on their plates altogether? How many meatballs are on the plates altogether? ** Total meatballs on the plates 3 x 3 = <<3*3=9>>9. How many meatballs are left on the plates altogether? ** If two-thirds are eaten, one-third remaining on the plates is 9 / 3 = <<9/3=3>>3. #### 3 Travis and his brother joined a trick-or-treat event. They collected 68 pieces of candy altogether. Each of them ate 4 pieces of candy after the event. How many pieces of candy were left? How many pieces of candy did they eat after the event? ** They ate a total of 4 x 2 = <<4*2=8>>8 pieces of candy after the event. How many pieces of candy are left? ** So, Travis and his brother have 68 - 8 = <<68-8=60>>60 pieces of candy left. #### 60 Alice and Emily are selling oranges at the farmer's market. Alice sold twice as many oranges as Emily did. In total, they sold 180 oranges. How many oranges did Alice sell? How many oranges did Emily sell? ** Emily sold 180/3=<<180/3=60>>60 oranges. How many oranges did Alice sell? ** Alice sold 60*2=<<60*2=120>>120 oranges. #### 120 Jimmy bought 3 pens for school for $1 each, 4 notebooks for $3 each and 2 folders for $5 each. If he paid with a $50 bill, how much change will he get back? How much did Jimmy spend on pens? ** Jimmy spent 3 * $1 = $<<3*1=3>>3 on pens. How much did Jimmy spend on notebooks? ** He spent 4 * $3 = $<<4*3=12>>12 on notebooks. How much did Jimmy spend on folders? ** He spent 2 * $5 = $<<2*5=10>>10 on folders. How much did Jimmy spend in total? ** He spent $3 + $12 + $10 = $<<3+12+10=25>>25 in total. How much change will Jimmy get back? ** His change will be $50 - $25 = $<<50-25=25>>25. #### 25 Ten boys brought 15 popsicle sticks each. Twelve girls brought 12 popsicle sticks each. How many fewer popsicle sticks did the girls bring than the boys? How many popsicle sticks did the boys bring? ** The boys brought a total of 10 x 15 = <<10*15=150>>150 popsicle sticks. How many popsicle sticks did the girls bring? ** The girls brought a total of 12 x 12 = <<12*12=144>>144 popsicle sticks. How many fewer popsicle sticks did the girls bring than the boys? ** Therefore, the girls brought 150 - 144 = <<150-144=6>>6 fewer popsicle sticks than the boys. #### 6 John runs a website that gets 30000 visits a month, for a normal 30 day month. He gets $.01 per visit. How much does he make per day? How many visits does John get per day? ** He gets 30,000/30=<<30000/30=1000>>1,000 visits per day How much does John make per day? ** So that means he makes 1000*.01=$<<1000*.01=10>>10 per day #### 10 You start a business selling charm bracelets. You spend $1 on the string for each bracelet and $3 on beads for each bracelet. You sell the bracelets for $6 each. If you sell 25 bracelets, how much profit will you make? How much does it cost to make each bracelet? ** It costs $1 + $3 = $<<1+3=4>>4 to make each bracelet. How much does it cost to make 25 bracelets? ** Your total cost is 25 * $4 = $<<25*4=100>>100. How much do you sell the bracelets for? ** Total revenue is 25 * $6 = $<<25*6=150>>150. How much profit will you make? ** Total profit is $150 - $100 = $<<150-100=50>>50. #### 50 Lance has 70 cents, Margaret has three-fourths of a dollar, Guy has two quarters and a dime, and Bill has six dimes. How many cents do they have combined? How much money does Margaret have? ** Margaret has 100 * 0.75 = $0.75. How much money does Guy have? ** Guy has $0.25 + $0.25 + $0.10 = $<<0.25+0.25+0.10=0.60>>0.60. How much money does Bill have? ** Bill has 6 * $0.10 = $<<6*0.10=0.60>>0.60. How many cents do they have combined? ** Lance, Margaret, Guy and Bill have $0.70 + $0.75 + $0.60 + $0.60 = $<<0.70+0.75+0.60+0.60=2.65>>2.65. How many cents do they have combined? ** Thus they have $2.65 * 100 = <<2.65*100=265>>265 cents. #### 265
