Median age of women at first marriage. In general, people in our society are marrying at a later age. The median age, A ( t ) , of women at first marriage can be approximated by A ( t ) = 0.08 t + 19.7 , where t is the number of years after 1950. Thus, A ( 0 ) is the median age of women at first marriage in 1950, A ( 50 ) is the median age in 2000, and so on. a. a) Find A ( 0 ) , A ( 1 ) , A ( 10 ) , A ( 30 ) , and A ( 50 ) . b. What was the median age of women at first marriage in 2008? c. Graph A ( t ) .

Solution Summary: The author calculates the median age of women at first marriage for different values of A(t).
Median age of women at first marriage. In general, people in our society are marrying at a later age. The median age,
A
(
t
)
,
of women at first marriage can be approximated by
A
(
t
)
=
0.08
t
+
19.7
, where t is the number of years after 1950. Thus,
A
(
0
)
is the median age of women at first marriage in 1950,
A
(
50
)
is the median age in 2000, and so on.
a. a) Find
