The demand for cat food is given by d ( x ) = 140 e − 0.03 x where x is the number of units sold and d(x) is the price in dollars. find the revenue function. r ( x ) = incorrect syntax error find the number of units sold that will maximize the revenue. find the price that will yield the maximum revenue.

The answer is as follows:

Explanation:

Given that,

D(x) =140

Revenue Function, R(x) = x × D(x)

= 140x

For maximizing revenue,

R'(x) = 0

140 + 140x×(-0.03) = 0

(140-4.2x) = 0

x =

= ⇒ Number of units sold

Price =

= 51.50 ⇒ price that will yield the maximum revenue

it id the first and last option
