The owner of a small store buys coats for ​$55.00 each. Answer parts a and b. a. He sells the coats for ​$77.00 each. What percent of the purchase price is the sale​ price? The sale price is 140​% of the purchase price. b. The owner increases the sale price by the same percent that you found in part a when he buys jackets for ​$35 and sells them. How many jackets must the owner buy for the total jacket sales to be at least ​$340​?

Respuesta :

Th owner must buy 7 Jackets

Step-by-step explanation:

a. Purchase price=$55 , Sell Price= $77

  Sell Price = $55+$22

                   = Purchase price + 40*55/100

                   =Purchase price + 40% of Purchase price

                    =140% of purchase price

b. Purchase Price=$35

    Sell price=140%of $35

                    =140*$35/100

                    =$49

Number of Jackets required for the total sale to be $340 = $340/$49

                                                                                                =6.94

So We get the result by rounding off because Jackets cannot be in fraction, which is 7
