For the period 1985-2001, the average salary "y"(in thousands of dollars) per season of a Major League Baseball player can be modeled by y=7x^2-4x+392 where x is the number of years since 1985.

Write and solve an equation to find the year when the average salary was $1,904,000.

    Plug in 1,904,000 for y.
