Let the cost of the dress = D

4 + D =26/1.30, solve for D

D = **16 pounds- purchase price of the dress**

16 + 4 =20 pounds - cost of the dress and scarf.

4 + [100% x 4] + 16P =1.30 x 20

8 + 16P = 26 subtract 8 from both sides

16P =26 - 8

16P = 18 divide both sides by 16

P =18/16

P =1.125 - 1 x 100 =**12.5% - profit on the dress. So that:**

4+[100%x4] + [16x1.125] =20x1.30

8 + 18 = 26
