Answer:
The EAR you earn from the match is 100%.
Explanation:
Since a full 5 percent match will be received if 5 percent of your salary is invested, this implies that 100% will be earned by you from the match up to 5%.
For example, if 5 percent of your salary that you put in is $200, the East Coast Yachts will match the $200. This indicates that effective annual return (EAR) earned by you from the match is 100%.
Therefore, the EAR you earn from the match is 100%.
