X = -20p + 500
20p = 500 - x
p = (500 - x)/20

R = xp = x(500 - x)/20 = (500x - x^2)/20

X = - 20 p + 500
First we have to express p as a function of x:
20 p = - x + 500 / : 20
p = - x/20 + 25
The revenue:
R = x p
R = x ( - x/20 + 25 ) = - x²/20 + 25 x

<h2> ${7}^{3} (as \: a \: single \: power \: of \: 7)$ </h2>

Step-by-step explanation:

Given 

${7}^{4} \div 7$

Since,

${a}^{x} \div {a}^{y} = {a}^{x - y}$

Hence,

$= {7}^{4 - 3}$

$= {7}^{3} (ans)(as \: a \: single \: power \: of \: 7)$
