Find the selling price. Round to the nearest cent.

store's cost:$13.10

percent of markup: 10%

Answer:$14.41

Step-by-step explanation:

%gain = (sp-cp) / cp * 100

10 = (sp-13.10) / 13.10 * 100

131=100 (sp-13.10)

131/100=sp-13.10

1.31=sp-13.10

Add 13.10 to both sides of the equation

1.31+13.10=sp-13.10+13.10

Sp=14.41

10% of 13 is 1.3 so 13+1.3 = 14.3
