 Average price 2017-09-15 Annette pose la question :If I sold a widget at \$15.50 17.5% of the time and \$16.50 88.5% of the time what is the algebraic expression for that. How do I arrive at an average pricePenny Nom lui répond. Price increases and decreases 2009-09-02 craig pose la question :I work for an industry that bases it price increases and decreases on commodity pricing - Customer get confused on how/why we calculated new prices due to movement in the market - Price go up x% for every \$10 of movement in the market - For this example- Movement went down by \$30 and it is 2% for every \$10 - so price decrease was 6%. Customer's price is currently \$100. We say - \$100/1.06= new price of \$94.3 Customer says - \$100*.94= new price of \$94. They don't understand that if board went back up \$30 which would be 6% increase, they wouldn't be back at \$100 if they multiplied on the price decrease. \$94*1.06=\$99.64 vs. \$94.3*1.06=\$100 (Back to the original price) What is the best way to explain to customer besides using this example? Any help or info is appreciated. CraigVictoria West lui répond.
