Answer:
$210
Step-by-step explanation:
The first thing we can do is to add the $25 back on to the total cost.
25 + 115 = 140.
We do this because he Sam used a gift certificate on the ski's that are already 2/3 of the original price.
Now, to find the original price we can use this equation:
![\frac{2}{3} x = 140](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%20x%20%3D%20140)
X represents the original price.
To solve this equation you would flip 2/3 to 3/2 and multiply that by 140, as seen below:
![(\frac{3}{2}) \frac{2}{3}x = 140 (\frac{3}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B2%7D%29%20%5Cfrac%7B2%7D%7B3%7Dx%20%3D%20140%20%28%5Cfrac%7B3%7D%7B2%7D%29)
Now you can solve:
![x = \frac{420}{2} \\x = 210](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B420%7D%7B2%7D%20%5C%5Cx%20%3D%20210)
We can check this answer by multiplying 210 by 2/3
(210)(2/3) = 140
Remember, Sam used a gift certificate for $25
140 - 25 = $115
Therefore, the original price of the skis is $210.

Answer:
circumference is 18.84
area is 28.26
Step-by-step explanation:
circumference of a circle is
2πr where r is radius
= 6×3.14= 18.8
area of a circle is πr²
= 3×3×3.14
= 28.26
use π = 3.14
