FIGURING A 20% DISCOUNT
Suppose you walked into a store that advertised that all items could be
sold for 20% off its sticker price. Rather than trying to compute the new
price in your head, pull out your trusty 95LX and go into HP CALC. Now
press (MENU) Bus% (Business Percentages) and use the up arrow key to move
the cursor to "Percent of total...", the last line on the screen. Type
in 100 - 20 and press (ENTER). "Percent of total...." will now = 80%. You
want to find 80% of the marked price to determine the sale price. Move
the cursor two lines up to "Total amount....." Type in the total, say 97
dollars, and press (ENTER). Now simply press (F8) (PART) and you'll see
that the part of the total (the actual sale price) is 77.60.
Try another item. Say the original price is $52.95. Type 52.95 in at
the Total amount line and again press (F8). You'll see the new total: 42.36.
If you don't have two decimal points showing, press (MENU) Options Format
