Respuesta :
Normally, two packs of batteries cost $1.89*2=$3.78. The discounted price of $3.40 divided by the standard price of $3.78 for two packs is approximately .9, or 90 percent. Therefore, we have an approximately ten percent discount with the sale.
markdown = (change in price / original price) * 100
markdown = [(1.89 - 1.70) / 1.89] * 100
= [0.19 / 1.89] * 100
= [0.101] * 100
= 10.1 IS UR ANSWER OR 10
