Sharing Variables Between Menus
If you compare the MU%C menu and the MU%P menus, you’ll see that
they have two menu labels in common —
and
.
COST
COST
Shared variables
%CHG
PRICE
PRICE
%TOTL
M%C
M%P
MU%C
MU%P
The calculator keeps track of the values you key in according to those
labels. For example, if you key in
COST
and
PRICE
in the MU%C menu,
exit to the BUS menu, and then display the MU%P menu, the calculator
retains those values. In other words, the variables are
shared
between
the two menus.
Example: Using Shared Variables.
A food cooperative buys cases of
canned soup with an invoice cost of $9.60 per case. If the co-op
routinely uses a 15% markup on cost, for what price should it sell a case
of soup
?
