Look at the following examples. Your calculator must be in NORMAL mode, and the display should be set to IFKM El in order to get the exact results that we show: Example: Solution: In your furniture business, you like to see about a 95% mark up from your cost to the retail price of each item. A certain couch costs you $455.70. What price do you sell it for? 95 In 455.70 1= w!'In' MI Result: 888.62 As you work through the above solution, you store the mark-up in the MU register by pressing 95 12ndl ri . Then you store the cost in the CST register (455.70 F-I ) and compute the selling price by pressing viii MI . (The IM key always means "compute." Question: What is the margin on each of these couches that you sell? Solution: After solving the above example, simply press M MAN Result: 48.72 In the above examples you have learned two things: 1. To store a number in one of the four registers CST, SEL, MAR, and MU, all you need to do is key in the number and press the key that names the desired register. 2. To compute one of the four values CST, SEL, MAR, or MU, based on numbers that you have just stored, press followed by the key that names the value you wish to compute. Understanding the above two items is the beginning of learning to get the most out of the four functions fl , n , 26 in . [OM , and And this understanding about storing and computing also applies to the functions IT) , M , M, (Th , and 1 1 (five important functions available in FIN mode). Example: In the same furniture business described in the last example, your cost on a 4' x 6' oriental rug is $502.40. Using the same mark-up and margin, what is the selling price Solution: 502.40 El oam Result: 979.68 Notice that once a number is stored in one of these four registers, it only changes if you store a new number there or if you compute a new value (or if you press I2ndF) 0 , which "clears all" registers except M). After completing the last series of examples, the numbers in the four business calculation registers are as shown below: 95.00 48.72 979.68 502.40 MU MAR SEL CST ni To verify that these registers contain those numbers, you can use the [Rai (Recall) function. Press (2ndl [ROLI to see 502.40. Press 2nd [Raj gimil to see 979.68, 2nd [Rai MAR to see 48.72, and 2nd Raj (2ncIF) POI to see 95.00. 27

Look
at
the
following
examples.
Your
calculator
must
be
in
NORMAL
mode,
and
the
display
should
be
set
to
IFKM
El
in
order
to
get
the
exact
results
that
we
show:
Example:
In
your
furniture
business,
you
like
to
see
about
a
95%
mark
up
from
your
cost
to
the
retail
price
of
each
item.
A
certain
couch
costs
you
$455.70.
What
price
do
you
sell
it
for?
!'In'
Solution:
95
In
455.70
1=
w
MI
Result:
888.62
As
you
work
through
the
above
solution,
you
store
the
mark-up
in
the
MU
register
by
pressing
95
12ndl
ri
.
Then
you
store
the
cost
in
the
CST
register
(455.70
F
—
I
)
and
compute
the
selling
price
by
pressing
viii
MI
.
(The
IM
key
always
means
"compute."
Question:
What
is
the
margin
on
each
of
these
couches
that
you
sell?
Solution:
After
solving
the
above
example,
simply
press
M
MAN
Result:
48.72
In
the
above
examples
you
have
learned
two
things:
1.
To
store
a
number
in
one
of
the
four
registers
CST,
SEL,
MAR,
and
MU,
all
you
need
to
do
is
key
in
the
number
and
press
the
key
that
names
the
desired
register.
2.
To
compute
one
of
the
four
values
CST,
SEL,
MAR,
or
MU,
based
on
numbers
that
you
have
just
stored,
press
followed
by
the
key
that
names
the
value
you
wish
to
compute.
Understanding
the
above
two
items
is
the
beginning
of
learning
to
get
the
most
out
of
the
four
functions
fl
,
n
,
26
[OM
,
and
in
.
And
this
understanding
about
storing
and
computing
also
applies
to
the
functions
IT)
,
M
,
M,
(Th
,
and
1
1
(five
important
functions
available
in
FIN
mode).
Example:
In
the
same
furniture
business
described
in
the
last
example,
your
cost
on
a
4'
x
6'
oriental
rug
is
$502.40.
Using
the
same
mark-up
and
margin,
what
is
the
selling
price
Solution:
502.40
El
oam
Result:
979.68
Notice
that
once
a
number
is
stored
in
one
of
these
four
registers,
it
only
changes
if
you
store
a
new
number
there
or
if
you
compute
a
new
value
(or
if
you
press
I2ndF)
0
,
which
"clears
all"
registers
except
M).
After
completing
the
last
series
of
examples,
the
numbers
in
the
four
business
calculation
registers
are
as
shown
below:
95.00
MU
MAR
SEL
CST
48.72
979.68
502.40
To
verify
that
these
registers
contain
those
numbers,
you
can
use
the
[Rai
(Recall)
function.
