    A word problem on integrals

    I got the answer of about 4872 calcs and I want to be sure that I did it correctly.

    Rate of calculators produced
    dx/dt=5000(1-(100/(t+10)^2)

    Find how many are made from the beginning of the 3rd to the end of the 4th week.

    I took the derivative and got 5000(x^2+10x+100)/x+10 and took it from 3 to 5...is that process right?

    you mean the antiderivative, don't you?

    4872 calculators looks fine.

    Erm yeah that...ok good. I just didn't want to get the wrong integrands because the start of the 3rd and end of the 4th threw me off a bit but I thought 3 to 5 was right.
