I think it’s gonna be (3,5)
A.) The insurance company's payment is 80% of the total minus the $500 deductible, so:
(12500 - 500) * .8 = 9600
B.) To find the Copay, you do almost the same thing:
(12500 - 500) * .2 = 2500
C.) Mary's Total Cost: 2500 + 500 = 3000.00
Remember, the number of subsets of a set is 2

, where n is the number of elements in the set. Thus, it is 2³ = 8. If you want a proof for that, ask in comments below.
The square will be equal to the diameter of the circle. The circumference of a circle is π times the diameter, and the perimeter of the square is four times times that diameter...
C=πd
d=C/π
p=4d so
p=4C/π feet, since C≈99 ft and π≈3.14
p≈4(99)/(3.14)
p≈126.1 ft (to nearest tenth of a foot)
