The pric of a certain commodity is a function of supply and demand. The table below shows the price of commodity per barrel between 1995 and 2000. Find the average anual rate of change between 1998 and 2000.

Year Price/barrel
1995 $19
1996 $24
1997 $17
1998 $11
1999 $24
2000 $35

12 Its actually 3.2

To find the average annual rate of change between 1998 and 2000, we need to calculate the total change in price over this period and then divide it by the number of years.

First, let's calculate the change in price for each year:
- From 1998 to 1999: $24 - $11 = $13 increase
- From 1999 to 2000: $35 - $24 = $11 increase

Now, let's calculate the total change in price:
Total change = $13 + $11 = $24

Next, we calculate the number of years between 1998 and 2000:
Number of years = 2000 - 1998 = 2 years

Finally, we can find the average annual rate of change by dividing the total change by the number of years:
Average annual rate of change = $24 / 2 = $12

Therefore, the average annual rate of change between 1998 and 2000 is $12 per year.
