Hello everyone. I need help with the following problem. If anyone can give step by step details & a solution, I will be greatly appreciative. Thank you http://www.purplemath.com/learning/posting.php?mode=post&f=8#

1.) In 2000 a small farm had sales of $176,000.00. In 2010, the same farm had sales of $301,000.00.

(a) Assuming that the change was linear, write the equation(in Slope-Intercept Form) of the relationship where y is the sales (in thousands of dollars) and x is the time in years. Hint: It is better to consider 2000 as "year 0"(year zero) and write the first ordered pair as (0, 176) where the "176" is the sales in thousands of dollars.

(b) What exactly does the slope tell you about the rate of change in sales PER YEAR?

(c) Use your equation to predict the sales for the farm in the year 2015.

(d) Use your equation to estimate the year that sales for the farm will reach $500,000..
