Of course. A 15% mark down gets the 100, though.
Well, since we're talking percentages now anyaway, here's my standard text

About percentages in Excel
Niek Otten, July 26 2006
In Excel, percentages are stored as fractions; 15% is stored as 0.15, 100%
as 1. That makes it easy to calculate with; just multiply a number with a
percentage and you get what you need. No need to divide/multiply by 100. In
fact, if you see a calculation with percentages which has the number 100
somewhere in the formula; be very careful, it might be wrong or at least use
percentages in a way they weren't meant to be used in Excel.
The conversion to a fraction happens automatically if you enter the % sign:
if you enter "15%" (without the quotes) the value will be 0.15 and it will
be displayed as 15%. If you then enter 12 in the same cell, two things can
happen: It will be the number 12 or 12%. What happens in your case depends
on a setting:
Tools>Options, Edit tab, "Enable automatic percent entry" (only Excel2000
and newer).
All built-in functions of Excel and all the functions in Analysis Toolpak
use this representation of percentages: be careful when supplying parameters
to these functions; never use whole numbers (like 8), always use fractions
(like 0.08 or, even better, 8%).
