**Answer:**

A polygon is a plane figure with a least three straight sides and angles, and typically five or more.

**Answer:**

A, m < $69.43

**Step-by-step explanation:**

(Could be wrong, I'm just browsing through brainly and thought it looked easy)

I found the percentage of what they've raised by doing 552.5 * .12 (12 percent of 552.5)

This gave me 66.3

We now need to look for how much they need to raise, so you subtract 552.5 by 66.3 to get 486.2.

You need to find out how much each of the 7 members needs to raise to get 486.2, to do this divide 486.2 by 7 to get 69.45.

Ideally, they would raise just this amount and the correct answer would be an equal sign, but since that isn't an option and if they raised less than 69.45 individually they would fail, raising more than 69.45 would pass their goal. So A, more than 69.45 is the answer.
