Answer:
$625
$2500
Step-by-step explanation:
tax = percent of tax x income
0.2 x 3125 = 625

3125 - 625
Each petal of the region

is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length

, which implies the segment is subtended by an angle of

. This means the area of the segment is


This means the area of one petal is

, and the area of

is four times this, or

.
Meanwhile, the area of

is simply the area of the square minus the area of

, or

.
So



(provided these regions are indeed disjoint; it's hard to tell from the picture)
Where is the work????????????
