According to the given function, it is found that fewer than 38.1% of U.S. voters will use punch cards or lever machines starting from the year of 2004.

What is the function?

[tex]P(t) = -2.5t + 63.1[/tex]

In which t is the number of years after 1994.

It will be fewer than 38.1% when:

[tex]P(t) < 38.1[/tex]

Hence:

[tex]-2.5t + 63.1 < 38.1[/tex]

[tex]-2.5t < -25[/tex]

[tex]2.5t > 25[/tex]

[tex]t > 10[/tex]

Fewer than 38.1% of U.S. voters will use punch cards or lever machines starting from the year of 2004.
