Doing Calculations Using Menus - HP -18C Owner's Manual

DOing Calculations Using Menus
Many menus do calculations in much the same way as the previous
markup calculation. You use the menu keys both to store numbers
used in the calculations and to do the calculations.
Figure 1-8 illustrates using the MU%C menu to calculate the percent
markup on cost. Figure 1-9 shows another calculation using the
MU%C menu. This time, the calculation uses the COST and M%C to
calculate the PRICE.
