He has lost the previous files as he has been replacing them.
Explanation:
When you save a file in your computer, you need to save it with a name that is different from the names of the other files you have in the computer. If you save file with the same name of another file, you will replace that file and will lose the information you had. So according to this, as Jack is saving all his work for the class with the name of the course, it means that he has saved everything with the same name and he has lost the previous files because everytime he saves a new file he replaces the previous one.

Part A:
Given that three firms make up the entire wig manufacturing industry<span>. One has a 50% market share, and the other two
have a 25% market share each. The Herfindahl index of this industry is given by:
</span><span>The Herfindahl-Hirschman index (HHI)
is a commonly accepted measure of market concentration. It is
calculated by squaring the market share of each firm competing in a
market, and then summing the resulting numbers, and can range from close
to zero to 10,000.
Therefore, the Herfindahl-Hirschman Index is given by:

Part B:
Mane attraction, one of the firms with a 25% market share in the wig
manufacturing industry, leaves the market. This would cause the
herfindahl index for the industry to
increase.
The HHI increases as firms leaves the market. As firms leaves the market the shares of the market previously held by the leaving firms are shared amongst the remaining firms in the market thereby increasing the HHI.
For instance, assumint the firm with 50% of market share acquired additional 10% of the leaving firm's market share and the other firm with 25% acquired the remaining 15%.
The new HHI is given by:
</span><span><span>

Part C:
The largest possible value of the
herfindahl index is 10,000 because: an
index of 10,000 corresponds to a monopoly firm with 100% market share</span>.
