Amanda's problem with money

Question

Amanda borrowed money from her sister 3 months ago. She has been paying her back the same amount each month and currently owes her 60$. In 3 months she will have paid off her debt. Create a table 

 

Answer 1

$60/3=$20 per month

She pays her debt in six months; 6*$20=$120 owed

1st month: $120-$20=$100

2nd month: $100-$20=$80

3rd:$80-$20=$60

4th:$60-$20=$40

5th:$40-20=$20

6th:$20-$20=$0

Here's all the information. You can create your table as you like.
