Markup (or price spread) is the difference between the selling price of a good or service and cost. It is often expressed as a percentage over the cost.

Given:

cost = $9.00

percent markup = 30%

Let the selling price be x

The formula form percent markup is:

[tex]\text{ \% markup = }\frac{\text{ Selling price - cost}}{\cos t}\text{ }\times\text{ 100 \%}[/tex]

Substituting we have;

[tex]30\text{ = }\frac{x\text{ - 9}}{9}\text{ }\times100[/tex]

Solving for x:

[tex]\begin{gathered} \text{x - 9 = 2.7} \\ x\text{ = 11.7} \end{gathered}[/tex]

Hence, the selling price is $11.7

Answer: $11.7
