Th owner must buy 7 Jackets
Step-by-step explanation:
a. Purchase price=$55 , Sell Price= $77
Sell Price = $55+$22
= Purchase price + 40*55/100
=Purchase price + 40% of Purchase price
=140% of purchase price
b. Purchase Price=$35
Sell price=140%of $35
=140*$35/100
=$49
Number of Jackets required for the total sale to be $340 = $340/$49
=6.94
So We get the result by rounding off because Jackets cannot be in fraction, which is 7
The are of the circle is 3.14
Answer:
The answer is B if the octagon has side lengths of 8
we can see that the center is (-3, 3) and the radius is 9 units.

How to find the center and radius of the circle?</h3>
The general circle equation, for a circle with a center (a, b) and radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
Here we have the equation:
x^2 + y^2 + 6x = 6y + 63
Let's complete squares:
x^2 + y^2 + 6x - 6y = 63
(x^2 + 6x) + (y^2 - 6y) = 63
(x^2 + 2*3x) + (y^2 - 2*3y) = 63
Now we can add and subtract 9, (two times) so we get:
(x^2 + 2*3x + 9) - 9 + (x^2 - 2*3x + 9) - 9 = 63
(x + 3)^2 + (y - 3)^2 = 63 + 9 + 9 = 81 = 9^2
(x + 3)^2 + (y - 3)^2 = 9^2
Comparing with the general circle equation, we can see that the center is (-3, 3) and the radius is 9 units.
