Thank you in advance!!

A manufacturer of slacks has discovered that the number x of khakis sold to retailers per week at a price p dollars per pair is given by the​ formula, p=27-(x/300)^2

 

​(a) Write the weekly revenue​ R(x) as a function of x.

​(b) What is the domain of the nonnegative function​ R(x)?

​(c) Graph

yequals=​R(x)

on its domain.

number of pants sold per week = x        given

price of pants =27-(x/300)^2                   given

 

Revenue per week is the number of pants sold  *   the price

 

R(x)    =      x    *   [ 27-(x/300)^2 ]          domain  can be anything fro no pants sold ( 0 )    to infinty

 

Here is a graph......just look at the right hand side.....
