I do not believe so, no. theres interior angles and exterior angles. hope that helps!
30-8.25= 21.75
21.75/3.75= 5.8, you can't buy .8 of a soda so he could buy 5 sodas.
The given population models for the trees is given as:

It is required to find which forest will have a greater number of trees after 20 years and by how many.
To do this substitute t=20 in the equations of the models:


Hence, forest A has a greater number of trees after 20 years.
Calculate the difference:

It follows that forest A has a greater number of trees than forest B by 43 trees.
After 20 years, forest A has a greater number of trees than forest B by 43 trees.
