Question

Cost equation is C=16x+63.Total Revenue is : R=x^2 +326x-18,463.
Determine the profit equation (profit=revenue - cost)

Answer 1

I got stuck in this step:
P= (-x^2 +326x - 18,463) - (16x+63)
-x^2 + 326x - 18463 - 16x -63
-x^2 + 310x -18526

Answer 2

it looks to me like you already got the answer

Answer 3

unless you want to factor it

Answer 4

I dont know how to factor it since its a huge number

Answer 5

you can use the quadratic formula:

\[\frac{ - b \pm \sqrt{b^2 - 4ac} }{ 2a } \]

Answer 6

thats right, Thank you :)

Answer 7

np but imo when it just asked for profit equaiton i would just leave it as is without factoring
