4. 55 + 0.65*55 = $90.75
5. 90.75 * 0.25*90.75 = $113.44
6. 113.44 - 0.33*113.44 = $76.00

Step-by-step explanation:
Inscribed Angle Theorem
Inscribed angles measures are 1/2 of the arc they create.
m∠FJH x 2 = arc FH
Just take the 31° and double it.
Multiply both the numerator and denominator by , which is called the "conjugate" of :
Why do we pick this number? Recall the difference of squares factorization:
Now replace and . Then
So in your fraction, you end up with
Finally, just expand the product.
If the profit was 170 then 25 things were bought. since n is 25 you multiply it by 8 which is 200 and if you then subtract 30 the answer is 170
