selling price with 1st discount:

Selling price with discount on the 1st selling price:

-----------------

-----------------------------
The selling price changed by 45% minus $.05
--------------------------------------
I could be misreading this. Did he do a discount on
the discounted price? Or is he replacing the 1st discount
with a different discount?
Ignore my solution if you think the 2nd choice applies.
Sorry for any confusion
