Your sister gives you $125 to spend on lollies. If you spend $65 how much money would you have left over? 125-65=60



Zaeeda has bought her sister a new puppy. She has $500 in her bank account as she heads to the shops.




She first buys a dog bed for $60. How much money does she have left? Firstly I did 500-60=440




She then buys a bowl for $25. How much does she have left? 440-25=415,another way by doing is 40-25=15,then you just add the 4 hundred.




Then she buys 3 chew toys. Each toy costs $3.50. How much does she have left? Firstly I add the chewy Toys and then my answer for that is 10.50c, then I move on to do 415-10.50c=404.5




Finally she buys a diamond collar for the dog which costs $154.50. How much is left in her account at the end of the day? First I do 404-154.5=249.5, for an example I did 4-4=0,now nothing, then I move on to do 50,the five is from the 54,and the 0 is from 4-4=0,so that I made was 50,then I did 50-1=49,249.5
