<<8/2=4>>4 left after giving some puppies away How many puppies does John sell? ** He then keeps one so he sells 4-1=<<4-1=3>>3 puppies How much money did John make? ** That means he made 3*600=$<<3*600=1800>>1800 How much money did John profit? ** So his profit was 1800-300=$<<1800-300=1500>>1500 #### 1500 Anna puts three slices of ham in each sandwich. If she has 31 slices of ham, how many more slices of ham does she need to make 50 ham sandwiches? How many slices of ham does Anna need to make 50 sandwiches? ** Anna needs 3 x 50 = <<3*50=150>>150 slices of ham to make 50 sandwiches. How many more slices of ham does Anna need to make 50 sandwiches? ** Anna needs 150 - 31 = <<150-31=119>>119 more slices of ham #### 119 Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make? How many pearl beads does Nancy have? ** Nancy has 40 + 20 = <<40+20=60>>60 pearl beads. How many beads does Nancy have? ** So, Nancy has a total of 40 + 60 = <<40+60=100>>100 beads. How many stone beads does Rose have? ** Rose has 2 x 20 = <<2*20=40>>40 stone beads. How many beads does Rose have? ** So, Rose has 20 + 40 = <<20+40=60>>60 beads. How many beads do Nancy and Rose have altogether? ** Thus, Nancy and Rose have 100 + 60 = <<100+60=160>>160 beads altogether. How many bracelets can Nancy and Rose make? ** Therefore, they can make 160/8 = <<160/8=20>>20 bracelets. #### 20 A farmer has 46 chickens. Each chicken gives him 6 eggs a week. If he sells a dozen eggs for $3, how much money would he make in 8 weeks? How many eggs does the farmer get each week? ** The farmer gets 46 x 6 = <<46*6=276>>276 eggs a week. How many dozen eggs does the farmer get each week? ** That gives him 276/12 = <<276/12=23>>23 dozen eggs. How much money does the farmer make in one week? ** In one week, he makes 23 x 3 = $<<23*3=69>>69 How much money does the farmer make in 8 weeks? ** In 8 weeks, he makes $69 x 8 = $<<69*8=552>>552 #### 552 Trevor is currently 11 years old and his older brother is 20 years old. How old will Trevor be when his older brother is three times as old as Trevor is now? How old will Trevor's older brother be when Trevor is 11? ** When Trevor is 11, his older brother will be 11 x 3 = <<11*3=33>>33 years old. How old is Trevor's older brother? ** Trevor’s older brother is 20 - 11 = <<20-11=9>>9 years older than Trevor. How old will Trevor be when his older brother is 33? ** Since Trevor is 9 years younger, Trevor will be 33 - 9 = <<33-9=24>>24 years old. #### 24 Janet buys 45-pound containers of cat litter for $21 each. If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days? How many times will she change the box in 210 days? ** If she changes the box weekly, then in 210 days, she will change the box 210/7=<<210/7=30>>30 times. How many pounds of cat litter will she need in 210 days? ** At 15 pounds of litter for every box change, she will require 30*15=<<30*15=450>>450 pounds of cat litter in 210 days. How many containers of cat litter will she need? ** If she buys 45-pound containers, then for 450 pounds she will need to buy 450/45=<<450/45=10>>10 containers of litter. How much will it cost, in dollars, for her to buy enough litter to last 210 days? ** At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210 #### 210 Tony has $87.
