Aspruce tree was measured three years after sprouting at a bright of 3.87 feet after its sixth year the tree reached a height of 7.74 what is the constant rate

Step-by-step explanation:

The constant rate of growth is the slope of the line that models this situation.  We need to come up with 2 coordinates that model the info given.  After 3 years, the height was 3.87 feet.  In a coordinate pair, that is (3, 3.87).  Likewise with the other info.  After the 6th year, its height was 7.74 which is (6, 7.74) in a coordinate pair.  Filling in the slope formula to find the constant rate of growth:

That tells you that the growth rate of the tree is 1.29 feet per year.

to determine the unit cost your would divide the total cost by the number sold.
