how long will it take to save 10.00?

Question

Everyday on her way home from school, Jen used $1 to buy a bag of chips. The chips cost $0.75 and she saves the remaining quarter in her change jar. Jen buys 5 bags of chips per week. At this rate how long will it take to save $10.00?

Answer 1

First determine how much Jen makes in a week. $0.25 * 5 = $1.25.

 

Now determine how many weeks it will take to reach $10.

$10 / $1.25 = 8.

 

It will take Jen 8 weeks to reach $10 dollars by saving $.25 five times a week.

 

This answer assumes that Jen is getting a new dollar everyday and that she is not spending her money that she has saved to buy more chips.
