Answer:
P = 61.70 feets
Step-by-step explanation:
Based on the information given :
For fencing , We need to calculate the perimeter of the semicircle ;
Perimeter of a semicircle is given as :
P = πr + 2r
P = perimeter ; r = Radius = 12 feets
P = 12π + 2*12
P = 12π + 24
P = 61.699111 feets
P = 61.70 feets
To. Obtain how much.
We multiply the perimeter by the cost per feet.

Answer:
Original price= $3,200
Step-by-step explanation:
Giving the following information:
Purchase price= $2,816
Discount rate= 12% = 0.12
<u>To calculate the original price, we need to use the following formula:</u>
Original price= purchase price / (1 - discount rate)
Original price= 2,816 / 0.88
Original price= $3,200
The problem is asking how much each person will need to pay. Simplifying the problem into an equation with variables (an algorithm) will greatly help you solve it:
S = Sales Tax = $ 7.18 per any purchase
A = Admission Ticket = $ 22.50 entry price for one person (no tax applied)
F = Food = $ 35.50 purchases for two people
We know the cost for one person was: (22.50) + [(35.50/2) + 7.18] =
$ 47.43 per person. Now we can check each method and see which one is the correct algorithm:
Method A)
[2A + (F + 2S)] / 2 = [ (2)(22.50) + [35.50 + (2)(7.18)] ]/ 2 = $47.43
Method A is the correct answer
Method B)
[(2A + (1/2)F + 2S) /2 = [(2)(22.50) + 35.50(1/2) + (2)7.18] / 2 = $38.55
Wrong answer. This method is incorrect because the tax for both tickets bought are not being used in the equation.
Method C)
[(A + F) / 2 ]+ S = [(22.50 + 35.50) / 2 ] + 7.18 = $35.93
Wrong answer. Incorrect Method. The food cost is being reduced to the cost of one person but admission price is set for two people.
