Upper Elementary:

 

Question: Alice is saving up for a video game that costs $45.00. She gets $20.00 every Monday in allowance, but she spends $15.00 each week on lunch at school. How many weeks will it take for Alice to save up for the video game?

 

 

 

 

Answer: 9 weeks

 

Solution:  Each week, Alice gets $20.00 and spends $15.00. So, she can save $20.00 – $15.00 = $5.00 per week. She needs $45.00 to buy the video game, so she can save up that amount in $45.00 ÷ $5.00 per week = 9 weeks.
