Answer :

Solution

- The amount Michael withdraws every day is $40.

- The number of days it takes to withdraw $680 is given by:

[tex]\frac{\text{Total Amount Withdrawn}}{\text{Amount Withdrawn per day}}[/tex]

- Using the formula above, we have:

[tex]\frac{\text{Total Amount Withdrawn}}{\text{Amount Withdrawn per day}}=\frac{680}{40}=17\text{ days}[/tex]
