A company's revenue from selling x units of an item is given as R = 1000 x − 3 x 2 . If sales are increasing at the rate of 25 units per day, how rapidly is revenue increasing (in dollars per day) when 120 units have been sold?

Revenue is increasing at a rate of $280 per day.

Step-by-step explanation:

Revenue function is given as R = 1000x - 3x^2

The rate at which revenue is increasing is obtained by differentiating R with respect to x

R = 1000x - 3x^2

dR/dx = 1000 - 6x

when x = 120 units

dR/dx = 1000 - 6(120) = 1000 - 720 = 280 dollars per day
