Question

The percentage B(t) of women ages 25 and older in the United States who hold a bachelor's degree or higher t years after 1990 can be approximated by

B(t) = 0.48t + 18.

Using an inequality, determine those years for which more than 40% of women ages 25 and older in the United States will hold a bachelor's degree or higher.

Please help!!

Answer 1

he inequality to determine the years in which more than 40% of women ages 25 and older in the United States will hold a bachelor's degree or higher is:

0.48t + 18 > 40

Subtracting 18 from both sides:

0.48t > 22

Dividing both sides by 0.48:

t > 45.83

So, for years t greater than 45.83, more than 40% of women ages 25 and older in the United States will hold a bachelor's degree or higher.
