Question

Casey currently owes $500 to his parents. He plans to pay them $60 per month until it is

paid off. Sally also owes her parents money. She borrowed $600 from them and plans to
pay them back $80 per month. Is there a time when they will both owe their parents the
same amount of money?

Answer 1

They will both owe their parents $200 when Casey is paying his 5th month and Sally is paying on her 5th month.

Explanation:

If Casey pays 60 dollars after 5 months, he will have payed $300 dollars. He still needs to pay $200.(500-300) If Sally pays 80 dollars after 5 months, she will have payed $400 dollars. She still needs to pay $200. (600-400)
