PS , I am busy for last two week no time for blog.Finally, I brought Western Digital portable hard drive (160GB) at PC show .It cost $100 and 5 years warranty.I give Three Methods how count total amount (for yourself) at Restaurant when you pay individual when eat with your friends.
(maybe it can help you)Example , if your food cost $15.60 and your drink cost $3.50.Remember , Total service charge is 17% (10%+7%) Customer Service charge(10%) and GST(7%)
First Method(Faster Way)1) both add together then Multiple by 117%[( $15.60 + $3.50= $19.10)x117%=$22.35]Second Method (Fast way)1) Both add together ( $15.60 + $3.50= $19.10)2)Divide by 100 then Multiple by 117[($19.10/100 =0.191)X117= $22.35]Third Method(Slower way)1) Both add together ( $15.60 + $3.50= $19.10)2)Multiple by 17%($19.10x17%= $ 3.25 )3) Add together($19.10 + $3.25=$22.35)
