Callie has $500 in her savings account and she deposits 25 every week. Leah has $750 in his savings account and withdraw 20 every week. how many weeks will it take until Callie has more money

Answer :

Answer:

6 weeks

Step-by-step explanation:

let x be the number of weeks

callie = 500 + 25x

leah = 750 - 20x

500 + 25x = 750 - 20x

-250 = -45x

x = 5.556

after 6 weeks, callie has (500 + 25(6)) = $650

and leah has (750 - 20(6)) = $630
