Median family income in country x between 1990 and 1999 can be modeled by f(x)=1144.7(x-1990)+35,834 where x is the year. Determine the median income was $42,303.

I did it this way don't know if it's right

f(x)=1144.7(x-1990)+35,834

42,303-35,834 = 1144.7 - (x-1990) + 35,834

6469. 1144 7 - (x-1990). 35,834

.177=x-1990

The median income was $1144.7 every year

Thanks for all your help:-)
