Im pretty sure that the answer it is A. 7
because if you subtract 2 from 7 you get 5
The center of the circle is expressed as (h,k) in the standard form of equation. In this case, the diameter endpoints are <span>(-3, 8) and (7, 4). Hence the circle center has coordinates which are the midpoints of the two points.
x = (-3 + 7) /2 = 2
y = (8 + 4) /2 = 6
hence the center of the circle is (2,6)</span>

Step 1: 415(.15)
Step 2: 475 - 415(.15)
Step 3: 403.75
