Answer:
Step-by-step explanation:
marked down by 1/4 of the original price.
let x represent original price
original price - 1/4 of original price = sales price
x - 1/4x = 128
4/4x - 1/4x = 128
3/4x = 128
x = 128/(3/4)
x = 128 * 4/3
x = 512/3
x = 170.666 rounds to 170.67 <== original price
==============================
I hope I am understanding this one correctly...
let x = price the store paid
x + 1/2x = 170.67
2/2x + 1/2x = 170.67
3/2x = 170.67
x = 170.67 / (3/2)
x = 170.67 * 2/3
x = 341.34/3
x = 113.78 <=== what the store paid
===========================
the difference between the discount price..I am assuming this is the $ 128 from part A.....and what the store paid....113.78...from part B..
128 - 113.78 = $ 14.22 <==
I am not completely sure about B and C......B confused me.....and if B is wrong, so is C.

Answer:
F = 105
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is (n – 2)180.
This polygon has 6 sides so the sum of the interior angles is (6-2) * 180 =
720
Add up the angles
x-60 +x-40 +130 +120 +110 + x-20 +x-20 = 720
Combine like terms
4x +220 = 720
Subtract 220 from each side
4x+220-220 = 720-220
x = 500
Divide each side by 4
4x/4=500/4
x = 125
We want to find angle F
F = x-20
= 125-20
105
