Hey
I'm stuck on this word problem
Marginal revenue in thousands of dollars is: R'(x) = -0.6x + 7
where x is the number of units sold, in hundreds. Find the revenue if 350 units are sold, assume R(0) = 0
Okay so I did the anti derivative of the equation
with C equalling 0
(-0.6x^2)/2 + 7x/1 = Y
then substituted 350 into the equation
My answer was -34300, my text says the answer is 20825
Where have I gone wrong?????????
thanks in advance.
