The table shows the amount of money (in dollars) spent by a household on plants and flowers for certain years. Describe the rates of change in the number of dollars spent during the time period.
Year 2001 2002 2003 2004 2005
Amount 127 134 139 137 136
Spent (dollars)
I got:
$7/Year
The changes were
7 5 -2 -1
The average for the whole period is (7+5-2-1)/4 = 9/4 or $2.25/year

general questions on topics can best be addressed by careful study of the relevant material, both in your text and online. Broad essays on general topics aren't a productive use of tutors' time, so you probably won't get much help on such a request.
Once you get stuck on a particular item, state the question clearly so a correct answer can be provided.
To find the rates of change in the number of dollars spent, you'll need to calculate the difference in dollars spent between consecutive years.
Let's calculate the differences for each year:
- The difference between 2002 and 2001 is 134 - 127 = 7 dollars.
- The difference between 2003 and 2002 is 139 - 134 = 5 dollars.
- The difference between 2004 and 2003 is 137 - 139 = -2 dollars.
- The difference between 2005 and 2004 is 136 - 137 = -1 dollars.
To describe the rates of change, we can say:
- From 2001 to 2002, the amount spent increased by $7.
- From 2002 to 2003, the amount spent increased by $5.
- From 2003 to 2004, the amount spent decreased by $2.
- From 2004 to 2005, the amount spent decreased by $1.
Based on the differences, it seems like the rate of change varies each year. Specifically, there was an increase of $7 and $5 in two consecutive years, but then a decrease of $2 and $1 in the following years. Therefore, it is not accurate to say that the rate of change is a constant $7 per year. Instead, we can describe the rates of change over the given time period as varying.
