Respuesta :

The correct option regarding the average rate of change for glass is given by:

c. From 1970 to 1980, the number of pounds of glass per person per day increased by 0.002 per year.

What is the average rate of change of a function?

It is given by the change in the output divided by the change in the input.

Looking at the table, in the 10 years from 1970 to 1980, the amount of glass changed from 0.34 pounds to 0.36 pounds, hence the rate is given by:

r = (0.36 - 0.34)/10 = 0.02/10 = 0.002.

Which means that option c is correct.
