3500 * 25
1=(%) - 2625.
Discount the sum of 168, 98, and 734 by 20%. (800)
168 + 98 + 734 =
K1~(STO) -(A)
S-(A) * * 20 1=(%) - 800.
* As shown here, if you want to use the current Ans (answer) memory
value in a mark up or discount calculation, you need to assign the
Ans memory value into a variable and then use the variable in the
