A company's revenue from selling x units of an item is given as R=1700x-2x^2 . If sales are increasing at the rate of 25 units p
viva [34]

Answer:

The daily rate is: 17500 units per day

Step-by-step explanation:

Given

R = 1700x - 2x^2

\frac{dx}{dt} = 25

Required

Find \frac{dR}{dt} when x = 250

We have:

R = 1700x - 2x^2

Differentiate both sides with respect to time

\frac{dR}{dt} = 1700\frac{dx}{dt} - 4x\frac{dx}{dt}

Factorize

\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}

Substitute: \frac{dx}{dt} = 25 and x = 250

\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}

\frac{dR}{dt} = (1700- 4*250)*25

\frac{dR}{dt} = (1700- 1000)*25

\frac{dR}{dt} = 700*25

\frac{dR}{dt} = 17500
