How many friends did Shelly make from after-school clubs? ** Shelly made 6 /2 =

<<6/2=3>>3 friends from after-school clubs. How many new friends did Shelly make at school this year? ** She made 6 + 3 = <<6+3=9>>9 new friends at school this year. How many inches of thread does Shelly need? ** Shelly will need 9 * 12 = <<9*12=108>>108 inches of thread to make each friend a keychain. #### 108 Amanda and her family are going to re-paint all the walls inside their house. Before they get started they want to divide up the work. Since all the rooms in the house have different numbers and sizes of walls in them, they figure the fairest way to divide up the work is to count all the walls in the house and assign an equal number to each person. There are 5 people in Amanda's family, including herself. There are 9 rooms in the house. 5 of the rooms have 4 walls each. The other 4 rooms each have 5 walls each. To be fair, how many walls should each person in Amanda's family paint? How many walls are in the house? ** First, Amanda needs to figure out how many walls there are in the house, 5 rooms x 4 walls each = <<5*4=20>>20 walls. How many walls are in the other 4 rooms? ** The other 4 rooms have x 5 walls each = 20 walls. How many walls are in the house? ** The house has 20 walls + 20 walls = <<20+20=40>>40 walls total. How many walls should each person paint? ** To divide the work equally between the 5 people, 40 walls / 5 people = <<40/5=8>>8 walls for each person. #### 8 On Wednesday, 37 students played kickball. On Thursday, 9 fewer students played kickball. How many students played kickball on Wednesday and Thursday? How many students played kickball on Thursday? ** 37 - 9 = <<37-9=28>>28 students played kickball on Thursday. How many students played kickball on Wednesday and Thursday? ** So, 37 + 28 = <<37+28=65>>65 students played kickball on Wednesday and Thursday. #### 65 To try to get the class to eat more vegetables, the teacher says that she will start giving them good character points that the class can redeem for a movie day if they earn enough. The students need to earn 200 points to win the movie day. Each time a student eats their vegetables at lunch she gives the student 2 points. There are 25 students in the class. If they have two school weeks, otherwise known as 10 days to win the movie, what is the average number of vegetables each student must eat per school week to get a movie day? How many points do the students need to earn? ** The students need eat 100 vegetables in total because 200 / 2 = <<200/2=100>>100 How many vegetables does each student need to eat? ** Each student needs to eat on average 4 vegetables because 100 / 25 = <<100/25=4>>4 How many vegetables does each student need to eat per school week? ** Each student needs to eat 2 vegetables per school week because 4 / 2 = <<4/2=2>>2 #### 2 A crate can hold 20 kilograms of tomatoes. Tommy has 3 crates which he bought for $330. He wants to sell the tomatoes for $6 per 1 kilogram but 3 kilograms of tomatoes were rotten. How much will be Tommy's profit from selling those tomatoes? How many kilograms of tomatoes does Tommy have? ** Tommy has a total of 20 x 3 = <<20*3=60>>60 kilograms of tomatoes. How many kilograms of tomatoes can be sold? ** Only 60 - 3 = <<60-3=57>>57 kilograms can be sold. How much will be Tommy's earnings from selling those tomatoes? ** His earnings for the tomatoes will be $<<342=342>>342. How much will be Tommy's profit from selling those tomatoes? ** Thus, his profit will be $342 - $330 = $<<342-330=12>>12. #### 12 Stephen ordered 2 large pizzas, both cut into 12 slices. He ate 25% of the pizza. His friend Pete ate 50% of the remaining pizza. How many slices are left over? How many slices are in each pizza? ** He ordered 2 pizzas, each cut into 12 slices so that’s 2*12 = <<2*12=24>>24 slices How many slices did Stephen eat? ** Stephen ate 25% of the pizza so he ate .25*24 = <<25*.01*24=6>>6 slices How many slices are left over? ** That leaves 24-6 = <<24-6=18>>18 slices How many slices does Pete eat? ** 18 slices are left and Pete eats 50% of 18 slices so he eats 18*.50 = <<18*50*.01=9>>9 slices How many slices are left over? ** If there were 18 slices and Pete ate 9 slices then there are 18-9 = <<18-9=9>>9 slices left over #### 9 There are 6 boxes of crayons that hold 8 orange crayons. There are 7 boxes of crayons that have 5 blue crayons. There is 1 box of 11 red crayons. How many crayons are there in total? How many orange crayons are there? ** 6 * 8 = <<6*8=48>>48 orange crayons How many blue crayons are there? ** 7 * 5 = <<7*5=35>>35 blue crayons How many red crayons are there? ** 11 red crayons How many crayons are there in total? ** 48 + 35 + 11 = <<48+35+11=94>>94 How many crayons are there in total? ** There are a total of 94 crayons. #### 94 Jocelyn bought a car 3 years ago at $4000. If the car's value has reduced by 30%, calculate the current value of the car. How much has the car's value reduced by? ** If Jocelyn bought the car 3 years ago at $4000, the car's value has reduced by 30/100*$4000=$1200 What is the current value of the car? ** The current value of the car is $4000-$1200 = $<<4000-1200=2800>>2800 #### 2800 Maximoff's monthly bill is $60 per month. His monthly bill increased by thirty percent when he started working at home. How much is his total monthly bill working from home? How much does Maximoff pay in additional fees? ** He pays an additional $60 x 0.30= $<<60*0.3=18>>18 on his monthly bill working from home. How much does Maximoff pay in total? ** Therefore, the total amount he pays for his monthly bill working from home is $60 + $18= $<<60+18=78>>78. #### 78 A leaf is being blown down a sidewalk by swirling gusts of wind. For every five feet that a gust blows it forward, the wind swirls and blows it back two feet. How many feet has it traveled down the sidewalk after 11 gusts of wind? How many feet does the leaf travel forward? ** Each gust blows the leaf forward 5 feet, so 11 gusts will blow it forward 5 * 11 = <<5*11=55>>55 feet. How many feet does the leaf travel back? ** Each swirl after a gust blows it back 2 feet, so 11 swirls will blow it back 2 * 11 = <<11*2=22>>22 feet. How many feet has the leaf traveled down the sidewalk after 11 gusts of wind? ** After 11 gusts, the leaf has traveled 55 - 22 = <<55-22=33>>33 feet down the sidewalk. #### 33
