Answer

Megan was $7$ under par.

Work Step by Step

The term "over" suggests the addition of a par while the term "under" suggests the subtraction of a par during the tournament. These are the rounds shot by Megan: $+3$, $-2$, $-3$ and $-5$ Add the rounds up: $= (+3) + (-2) + (-3) + (-5)$ $= 3 - 2 - 3 - 5$ $= 3 - 5 - 5$ $= 3 - 10$ $= -7$ Therefore, Megan was $7$ under par.
