Problema Solution
On the basis of data form 1990 to 2006 the median income y in year x for men and women is approximated by equations given below where x=o corresponds to 1990 and y is in constant 2006 dollars. If these equations remain valid un the future when will the median income of men and women be the same? Men -249x+2y= 56396 Women -833x+3y=47754
Answer provided by our tutors
For men:
-249x+2y= 56396
y = (1/2)(56396 + 249x)
For women:
-833x+3y=47754
y = (1/3)(47754 + 833x)
we need to find x such (1/2)(56396 + 249x) = (1/3)(47754 + 833x)
by solving the equation:
(1/2)(56396 + 249x) = (1/3)(47754 + 833x)
we find:
x = 80.17 years

80.17 corresponds to the year of 1990 + 80.17 = 2070.
