Example A: Calculate the net price of merchandise listed at $800 less a discount of 25%. Greek letter
Sigma in
Solution algorithm: mathematics is
used to denote
$800 list price (or invoice price) x 25% =
(as a decimal) $800 x 0.25 = $200 or instruct that
all numbers of
the set are
$800 List Price
− $200 Discount as a percent added together
for a Total Sum.
$600 Net Price

With your hand held calculator and using the % key:

Solution: Cl/C 800 − 25 % —> 600 —> means $600

Without the % key with the percent as a decimal:

Solution: Cl/C .25 X 800 M+ 800 − MR = 600 —> means $600

Example B: Calculate the net price of merchandise listed at $800 less a discount of 25%.

Solution algorithm: Compliment
$800 list price (or invoice price) x (100% − 25%=) 75% =
(as a decimal) $800 x 0.75 = $600

With your hand held calculator and using the % key:

Solution: Cl/C 800 x 75 % —> 600 —> means $600

Without % key:

Solution: Cl/C 1 − .25 X 800 = 600 —> means $600

Example C: Calculate the net price of merchandise listed at $800 less a volume discount
of 13%, a duty discount of 9%, and a cash discount of 8%.

Solution algorithm:
List price  D1-n = net price

$800 list price (or invoice price)  (100% − (13%, 9%, 8%) ) =
$800 list price (discounts as decimals)  (1.00 − (0.13 + 0.09 + 0.08) ) =
Compliment calculation $800  (1.00 – 0.30) =
Compliment $800  0.70 = $560

With your hand held calculator and using the % key:

Solution: Cl/C 800 x 70 % —> 560 —> means $560

— OR —

Solution: Cl/C 800 − 30 % —> 560 —> means $560
