A department store has a discount on shoes based on percentage of the price. Suppose one pair of shoes is marked down 70$ to 49$ what is the price for a 110$ pair of shoes after the discount is applied

1. A department store has a discount on shoes based on percentage of price.

=> one pair of shoes marked down from 70 dollars to 49 dollars

=> let’s solve for the percentage rate.

=> 70 - 49 = 21, the than ½ of the price

=> 70 x 30% = 21

Thus, the percentage rate is 30%

For the pair of shoes that is 110 dollars

=> 110 *.30 = 33

=> 110 - 33 = 77

Thus, the price of pair of shoes is now 77 dollars.
