Answer 1

For male doctors, the starting percentage is `98%`, but it decreases by `0.54%` each year.
Thus, the equation for the percentage of male doctors is:
`y = -0.54x + 98`
where `y` is the percentage of male doctors and `x` is the number of years it has been since `1960`.

For female doctors, the starting percentage is `2%`, but it increases by `0.54%` each year.
Thus, the equation for the percentage of female doctors is:
`y = 0.54x + 2`
where `y` is the percentage of female doctors and `x` is the number of years it has been since `1960`.
