Marsh has $23,479 in the bank. If she withdraws 25% of her total, what percent of the new total must she deposit to give her the same total as she started with?

If she withdraws 25%, 75% remains:

23,469 x 0.75 = 17,601.75

Divide original amount by amount left:

23,469 / 17,601.75 = 1.333

Using the decimal 0.33333 multiply by 100 to get 33.333%

She will need to deposit 33 1/3%
