The number of visits to public libraries increased from 1.2 billion in 1990 to 1.6 billion in 1994. Find the average rate of change in the number of public library visits from 1990 to 1994.

Respuesta :

Okay, here we have this:

Considering the provided information, we are going to calculate the requested rate of change, so we obtain the following:

We will replace in the rate of change formula with the following points: (1990, 1.2) and (1994, 1.6), then we have:

Rate of change=(f(b)-f(a))/(b-a)

Rate of change=(1.6-1.2)/(1994-1990)

Rate of change=0.4/4

Rate of change=0.1 Billion

Finally we obtain that the average rate of change in the number of public library visits from 1990 to 1994 is 0.1 billion.
