Answer:
---------------------
Initial number of pairs of shoes is 20.
To achieve 50 pairs Mindy needs 30 more pairs.
Each week 2 pairs added but 1 removed. It makes total of 1 pairs addition.
After 28 weeks Mindy will have 20 + 28 = 48 pairs of shoes.
The next week he will purchase 2 more pairs and get 50 pairs in total.
The number of weeks it will take for her closet to have 50 pairs of shoes would be = 30 weeks.
A purchase price is the amount of money that was use to obtain a valuable.
The number of shoes owned by Mindy = 20 pairs
The number of shoes Mindy purchases per week = 2 pairs
The number of shoes Mindy destroys = 1 pair.
Therefore, in a week Mindy has an additional 1 pair of shoe.
The number of pairs she needs extra = 50-20 = 30
Since 1 pair of shoe = 1 week, she will require 30 weeks to purchase additional 30 pairs making it up to 50 pairs of shoes she owns.
