Answer:

$180.83

Explanation:

number of clients = 1900

charge per client = $45

increase by $1 leads to loss of 6 clients

let the increase in charge be represented as : X

loss of clients = 6X

therefore revenue generated ( Rx) = ( $45 + X ) (1900 - 6X)                                                                       =                                                             ( 45 * 1900 - 45(6X) + 1900X - 6[tex]x^{2}[/tex])

                                                          = 85500 - 270X + 1900X - 6[tex]x^{2}[/tex]

R(x) = - 6[tex]x^{2}[/tex] + 1630 x  + 85500

find x = [tex]\frac{-b}{2a}[/tex] = [tex]\frac{-1630}{2(-6)} = \frac{-1630}{-12}[/tex] = 135.83

to optimize the revenue from monthly dues will be

charge per client + X = $45 + $135.83 = $180.83
