Question

a survey of 2000 doctors showed that an average of 3 out of 5 doctors used brand x aspirin. how many doctors use brand x aspirin (solve for x)

Answer 1

1,200 doctors use brand X aspirin

Explanation:

Out of the 2,000 doctors, the survey showed that 3 out of 5 use brand X. So that means
`(3)/(5)` of 2000 doctors use Brand X. So the proportion will then be lke this:

`(3)/(5) = (x)/(2000)`

So we can now solve for x using this equation:

`(3)/(5) = (x)/(2000)\\\\((2000)(3))/(5) = x\\\\(6000)/(5) = x\\\\1200 = x`
