The given question is related to Equations.
The correct equation to determine the athlete's salary this year is S = 890,000 / 0.7, which is option D.
To find the athlete's salary this year, we need to divide the salary of last year by the percentage of the salary this year. In this case, the athlete's salary last year was $890,000, which is 70% (0.7) of her salary this year. So, dividing $890,000 by 0.7 will give us the athlete's salary this year.
