For now I will say +289.5+=+x+
-------------------
Reg price = +x+
After 3 wks:
+x+-+.2x+=+.8x+
-------------------
After 6 wks:
+.8x+-+.3%2A%28+.8x+%29+=+.8x%2A%28+.7+%29+=+.56x+
After 7 wks:
+.56x+-+.1%2A%28+.56x+%29+=+.56x+-+.056x+
+.504x+
-------------
The price after 8 weeks is:
+.504%2A289.5+=+145.908+
$145.91
-------------
