Answer: This is an example of Limited Problem Solving.
Explanation:
Jenn changed the locks after each tenant moves out so that if they made keys to the old locks they will not be able to enter. If she had other options such as key cards she could save money and time in the future.
Jenn could also purchase the locks in bulk and this can save time and money also. Buy buying in bulk, she would have the product on hand when needed. She would save time by eliminating the need to go to the store each time. There is always a probability that the store will not have what she needs and will have to spend time looking at other places for the locks.
