There are some questions about this problem.
The first question is: what sports equipment should be allocated in the empty space? The answer is the sports center should be given more treadmills, even though 10 treadmills are already in the sports center. Demand for treadmills is high, and students seem to use them more.
The second question is: why should arm curls be removed? The answer is two arm curls were found in the sports center while checking inventory, but those are not used fully. For this reason, it should be less than two.
The third question is: if you use management science, what kind of sports center problem can be solved? The answer could be, for example, 'How many people can be hired for cleaning and how to arrange them in the proper area?'.
