Christmas stockings are knocked down 10 percent. the sale price is $2.00. what was the original price of the stocking? explain your answer.

~$2.22

the stockings are 90% of the original price (100% - 10% = 90%)

normally, you would take the original price, then multiply by (1 - discount) to find the new price. since we are working backwards, we do the inverse operation (divide.)


that gives you the original price.
