Alinara [238K]

Answer

Find out the  selling price of the scrapbook kit .

To prove

As given

I craft store retailer uses a markup rate of 65%.

A scrapbook kit cost $20 .

Than 65% is written in the decimal form.

= \frac{65}{100}

= 0.65

Mark up price = 0.65 × 20

                       = $ 13

Selling price of Scrapbook kit = Cost of Scrapbook kit + Mark up price.

                                                 = 13 + 20

                                                = $33

Therefore the  the selling price of the scrapbook kit $33.
