Question

The percentage of households that owned a videocassette recorder (VCR) in the United States, f(t), each year from 1980 to 1995 can be modeled by the function f, where t is the number of years after 1980. Which of the following is the best interpretation of f(10) = w, where w is a constant, in this context?

A) In 1990, there were w households in the United States that owned a VCR.
B) In 1990, w% of households in the United States owned a VCR.
C) The percentage of households in the United States that owned VCR w years after 1990 was 10.
D) There were 10 times more households in the United States that owned a VCR w years after 1980 than in 1980.
