The revenue from selling x units of a product at a price of p dollars per unit is given by xp, for a particular commodity, the revenue is r=800x-0.25x^2. factor the expression for the revenue and determine an expression for the price in terms of x

> Factor the expression for the revenue

We are given that the revenue is the product of price and number of units sold = x p. Given the equation of revenue we factor it:

R = 800 x – 0.25 x^2

Take out x from the equation:

R = x (800 – 0.25 x)

We see that this is now in the form x p

> Determine an expression for the price in terms of x

From the factored equation we can say that the price in terms of x is:

p = 800 – 0.25 x

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
