The Pocket Money Problem Week 4 T1 2014
Now Shreya has turned 8 years old her parents said they would be giving her $4.50 each week as pocket money because she did her chores so independently. She was very excited. She wants to save her money to buy a doll that costs $54.00.
Questions:
1. How much money would she have after 5 weeks?
2. How much money would she have after 10 weeks?
Extra challenge:
3. How m
any weeks’ pocket money would she need to save to pay for the special doll she wants. The doll costs $54.00.
This is how I worked out how much Shreya would have after 5 weeks: $4.50+$4.50=$9.00 $4.50+$4.50=$9.00 $9.00+$9.00=$18.00 $18.00+$4.50=$22.50 
After 10 weeks Shreya would have: $45.00 This is how I worked it out: $22.50+$22.50=$45.00 
Extra challenge:
How many weeks’ pocket money would she need to save to pay for the special doll she wants. The doll costs $54.00. This is how I worked it out: In 10 weeks she had $45.00. In 12 weeks she has $54.00. I did 10 weeks which is $54.00 + 2 weeks which is $9.00 so this = $54.00. 
I learned how to use a grid when problem solving
