1 answer

To find the rate of change of the number of entertainment websites from 1995 to 2004, we can use the formula:

\[ \text{Rate of change} = \frac{\text{Change in quantity}}{\text{Change in time}} \]

  1. Change in quantity: Number of websites in 2004 - Number of websites in 1995 = 793 - 54 = 739

  2. Change in time: 2004 - 1995 = 9 years

Now, substitute these values into the formula:

\[ \text{Rate of change} = \frac{739}{9} \approx 82.1111 \]

Rounding to two decimal places gives approximately 82.11 websites per year.

Therefore, the closest answer to this value is:

A. 82 websites per year.
