    Answer:

    1,200 doctors use brand X aspirin

    Step-by-step explanation:

    Out of the 2,000 doctors, the survey showed that 3 out of 5 use brand X. So that means \frac{3}{5} of 2000 doctors use Brand X. So the proportion will then be lke this:

    \dfrac{3}{5} = \dfrac{x}{2000}

    So we can now solve for x using this equation:

    \dfrac{3}{5} = \dfrac{x}{2000}\\\\\dfrac{(2000)(3)}{5} = x\\\\\dfrac{6000}{5} = x\\\\1200 = x
