Answer:
$465
Explanation:
To know how much the General Hospital charges Cigna, we will use the following equation:
[tex]\text{ Marked price = Cost price \lparen1 + Mark up\rparen}[/tex]So, replacing the cost price = $150 and the mark up = 210% = 2.1, we get:
[tex]\begin{gathered} \text{ Marked Price = 150\lparen1 + 2.1\rparen} \\ \text{ Marked Price = 150\lparen3.1\rparen = 465} \end{gathered}[/tex]Therefore, the answer to question A is $465.
