Answer:
Stepbystep 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.
