What do I need to find?
The difference in the number of bean plants that were 9in tall and the combination of 7in and 8in tall plants.
What information do I need to use?
Number of bean plants 9in tall: 12 plans
Number of bean plants 7in or 8in tall:
7in: 9plants
8in: 8plants.
7in or 8in: 17 plants
How will I use the information:
Subtract the number of bean plants 9in tall from the number of plants 7in or 8in tall:
[tex]17-12=5[/tex]
Then, there are 5 9in tall plants less than the combination of 7in and 8in plants
