The revenue R (in thousands dollars) for a business is modeled by the equation
`R=x^3-6x^2+x+75` , where x is the number of years since 2000. The cost C (in thousands dollars) for this business is modeled by the equation
`C=x^2-70x` .

Which equation represents the profit, P, for this business?


`P=x^3-5x^2+71x+75`


`P=-6x^2+71x+75`


`P=x^3-7x^2+71x+75`


`P=x^3-5x^2+69x+75`

Answer 1

Profit would be the revenue minus the cost

so R=x^3-6x^2 +x +75 - C=x^2-70x =
