The total sales of a company in 2008 were \$45,000. In 2011, it grew to \$84,000. Use
 as the number of years since 2000 and  as the total sales, and answer the
following:
a. What is the rate of change (slope) in the total sales?
b. Write an equation in both point-slope form and slope-intercept form modeling
the company’s sales.
c. What are the projected sales for the year 2016? (16 years after 2000.)

• Math -

There are two points:
(8,45000) and (11,84000)

a, the rate of change is (84000-45000)/(11-8) = 28000/3

b, use the slope 28000/3 and a point, you can plug into the formulas

c, once you have the equation, plug in 16 then you will get the answer

• Math -

The above answer is wrong. (84000-45000) is not 28000, it is 39,000. Therefore 39000/3 is 13000. M =13000.
