Step-by-step explanation:
To predict how many stamps Mary might have in the year 2009 based on the given data, we can observe the trend in the number of stamps in Mary's collection over the years:
- From 2004 to 2005: increase of 5 stamps
- From 2005 to 2006: increase of 5 stamps
- From 2006 to 2007: increase of 5 stamps
- From 2007 to 2008: increase of 5 stamps
If this trend continues, we can expect an increase of 5 stamps in the following year, which would mean Mary would have 5 stamps in 2009.
Therefore, if the trend continues, Mary might have 5 stamps in the year 2009.
