In economics, revenue Upper R is defined as the amount of money derived from the sale of a product and is equal to the number x of units sold times the selling price p of each unit. If the selling price is given by the equation p -1/10x+60 , express revenue R function of the number x of units sold.

a.I made the the function equal to 0 and got 600 then I multiplied in x=600 into the function and got -60x+60.
But I don't get what I did or what it's asking me. Please Help

R = x * p

p=-1/10x + 60

function of R(x) :

R(x) = x * (-1/10x + 60)

What is the question asking?

To express the revenue function R in terms of the number of units sold (x), you need to multiply the selling price (p) by the number of units sold (x).

Given that the selling price is given by the equation p = -1/10x + 60, you can substitute this value of p into the revenue function.

Therefore, the revenue function is calculated as follows:
R = x * p

Replacing the value of p with -1/10x + 60:
R = x * (-1/10x + 60)

Now, you can simplify this expression by distributing the x:
R = -1/10x^2 + 60x

Thus, the revenue function R in terms of the number of units sold (x) is -1/10x^2 + 60x.

To express revenue (R) as a function of the number of units sold (x), we need to use the given selling price equation and multiply it by the number of units sold.

The selling price equation is given as: p = -1/10x + 60

To calculate revenue, we need to multiply the selling price (p) by the number of units sold (x).

R = x * p

Substituting the selling price equation into the revenue equation:

R = x * (-1/10x + 60)

Now, we can simplify and express the revenue function in terms of x:

R = -1/10x^2 + 60x

This is the expression for revenue (R) as a function of the number of units sold (x). It is a quadratic function with a negative coefficient for the x^2 term.
