Ariel deposited $600 into a bank account. each friday she will withdraw 10% of the money in the account to spend. ariel thinks her account will be empty after 10 withdrawals. do you agree? explain.

No  

Step-by-step explanation:

Ariel will always have some money remaining.

We can demonstrate this by designing a table.

Each week she starts with a certain amount. At the end of the week she deducts 10 %, and the amount remaining becomes the starting amount for the next week.

Week  Principal  Less 10 %  Remaining

    1       600.00      60.00        540.00

    2      540.00      54.00        486.00

    3      486.00       48.60        437.40

    4      437.40       43.74         393.66

    5      393.66       39.37        354.28

    6      354.28       35.43         318.85

    7       318.85        31.89        286.97

    8      286.97       28.70        258.27

    9      258.27      25.83         232.44

  10      232.44      23.24         209.20

Ariel will still have $209.20 in her account after 10 weeks.
