Jane brings 75% as many pieces of bread as treats to feed the live pets at the zoo. Wanda brings half as many treats as Jane and three times as many pieces of bread as treats. If Wanda brings 90 pieces of bread, what is the total number of pieces of bread and treats that Wanda and Jane brought to the zoo?

How many treats did Wanda bring? ** Wanda brought 90 pieces of bread, three times the number of treats, so Wanda brought 90/3 =

<<90/3=30>>30 treats. How many treats did Wanda bring? ** Wanda brought half as many treats as Jane, which means Jane brought 30*2 = <<30*2=60>>60 treats. How many pieces of bread did Jane bring? ** The total number of pieces of bread Jane brought is 75% of the number of treats, which means Jane brought 0.75 * 60 = 45 pieces of bread. How many pieces of bread and treats did Wanda and Jane bring? ** Wanda and Jane brought a total of 30 treats+60 treats+45 pieces of bread + 90 pieces of bread = <<30+60+45+90=225>>225 #### 225 Emmanuel will stay in Guam in December for 10 days in which he has to use international data that would cost $3.50 per day. Emmanuel has been paying $175 per month for his regular plan. How much in all will be Emmanuel’s charges for December? How much will the international charge cost? ** The international charge cost $3.50 x 10 = <<3.50*10=35>>35.

Her best friend Clara plays 2 fewer songs each day. If in June they didn't play any song during the weekends only, and there were 8 weekend days in June, what's the total number of songs they both listened to in that month? How many days did they play? ** June has 30 days, so if they didn't play any songs on weekends, then they played 30 days - 8 days = <<30-8=22>>22 days. How many songs did Vivian play? ** If Vivian played 10 songs each day, the total number of songs she played for the month is 10 songs/day * 22 days = <<10*22=220>>220 songs. How many songs did Clara play? ** Clara played 2 fewer songs, which is 10 songs/day - 2 songs/day = <<10-2=8>>8 songs/day. How many songs did Clara play? ** The total number of songs played by Clara for the whole month is 8 songs/day * 22 days = <<8*22=176>>176 songs. How many songs did Vivian and Clara play? ** The total played by both is 220 songs + 176 songs = <<220+176=396>>396 songs #### 396 Freddy is 2 years younger than Stephanie.

He knew 20% of the words on them. He has 40 days to learn the rest. How many words does he need to learn a day? How many words does Bo know? ** He knows 800*.2=<<800*.2=160>>160 words How many words does Bo need to learn? ** So he needs to learn 800-160=<<800-160=640>>640 words How many words does Bo need to learn a day? ** That means he needs to learn 640/40=<<640/40=16>>16 words per day #### 16 Mike is 16 years old. His sister Barbara is half as old as he is. How old is Barbara going to be when Mike is 24 years old? How old is Barbara currently? ** Barbara is currently 16 years / 2 = <<16/2=8>>8 years old. How old will Mike be after 24 years? ** Mike is going to be 24 years old after 24 years - 16 years = <<24-16=8>>8 years. How old will Barbara be when Mike is 24 years old? ** So Barbara is going to be 8 years + 8 years = <<8+8=16>>16 years old. #### 16 Val has three times as many dimes as nickels. If she accidentally finds twice as many nickels as she has in her older brother's treasure box, and takes them for herself, what would be the value of money she has, in dollars, if she had 20 nickels before finding the new ones from her brother's treasure box? How many more nickels does Val find than she has? ** If Val currently has 20 nickels and finds twice as many nickels as she has in her older brother's treasure box, she will have 2*20=40 more nickels. How many nickels will Val have after finding the new ones from her brother's treasure box? ** The total number of nickels she'll have is 40+20=<<40+20=60>>60 What is the value of the nickels Val is having? ** Since nickel is worth $0.05, the value of the nickels Val is having is 60*0.05=$<<60*0.05=3>>3 How many dimes did Val have before finding the new ones from her brother's treasure box? ** Val had three times as many dimes as nickels before she found the 40 new nickels, a total of 3*20=<<3*20=60>>60 dimes What is the value of the dimes Val has? ** Since a dime has a value of $0.10, the value of the dimes that Val has is 60*$0.10=$<<60*0.10=6>>6 What is the value of the dimes and nickels Val has? ** Together, the value of the dimes and nickels Val has is worth $6+$3=$<<6+3=9>>9 #### 9 If Amanda can run the length of a football field 2000 meters in length in 2 hours, how long would it take her to run the length of a 10000-meter track at the same speed? How fast does Amanda run the length of a football field? ** Running the length of a football field 2000 meters in 2 hours is a speed of 2000/2=<<2000/2=1000>>1000 meters per hour. How long would it take Amanda to run the length of a 10000-meter track? ** At the same speed, Amanda will run the length of a 10000-meter track in 10000/1000 = <<10000/1000=10>>10 hours #### 10 There were some snowflakes at first.

What percentage of her hair decorations are bobby pins, rounded to the nearest percent? How many barrettes are there? ** First find the total number of scrunchies: 6 barrettes * 2 = <<6*2=12>>12 scrunchies How many bobby pins are there? ** Then subtract three fewer bobby pins than barrettes 6-3 =<<6-3=3>>3 bobby pins How many hair decorations are there? ** Then add the number of each type of hair decorations to find the total number: 6 decorations + 12 decorations + 3 decorations = <<6+12+3=21>>21 decorations How many bobby pins are there? ** Then divide the number of bobby pins by the total number of decorations and multiply by 100% to express the answer as a percentage: 3 bobby pins / 21 decorations * 100% = 14.28 which rounds down to 14% #### 14
