The function Wx 007x 41 models the number of women Wx in m

The function W(x) = 0.07x + 4.1 models the number of women. W(x), in millions, enrolled in U.S. colleges x years after 1984. The function M(x) = 0.01x + 3.9 models the number of men. M(x), in millions, enrolled in U.S. colleges x years after 1984. a) Find the number (in millions) of women enrolled in U.S. colleges in the year 2002. b) Find the number (in millions) of men enrolled in U.S. colleges in the year 2002.

Solution

W(x) = 0.07x + 4.1

x = years after 1984

So in the year 2002

x = 2002 - 1984 = 18 yrs

no. of women will be

W(x) = 0.07*18 + 4.1 = 5.36 millions women

Similarly number of mens will be

M(x) = 0.01*18 + 3.9 = 4.08 millions men
