total revenue is the total amount of money taken in by a business.

Question

An appliance firm determines that when in sells x washing machines, the total revenue, R, in dollars, is given by the polynomial R=119.44x-0.22x^2. 

What is the total revenue from the sale of 256 washing machines?

Answer 1

In order to solve this problem, all you have to do is plug in 256 wherever you see an "x".

 

So you would have R=119.44(256)-.22(256)².

 

Remember your order of operations when dealing with the exponent.
