Question:

The difference, d, in median earnings, in $1000s, between high school graduates and college graduates can be approximated by d = -0.012x² + 0.828x + 15.750, where x is the number of years after 1980. Based on this model, estimate to the nearest year when the difference in median earnings was $25,000.
