f(x) = -2x^2 + 24x + 1280

 

This is a downward turning parabola........we can find the x coodinate of the vertex as

 

-24/ [ (2 (-2) ]  =    -24 / -4   =  6

 

This means that  the number of people that maximizes the revenue is  32 - 6   =  26

This is the answer to (2)

 

And for (1)....the max revenue is   

 

-2(6)^2 + 24(6) + 1280 =

 

-2(36) + 144 + 1280 =  $1352

 

 

 

cool cool cool
