Assuming that this is a linear relationship you must find the rate of change...$23.81-$20.70= $3.11. 3.11 is how much it changed that year. What that also gives you is how much you bought the post for at 0 years by subtracting $20.70 and the $3.11 = the price of the poster. This gives us the equation y=3.11(x)+17.59
Where Y is the value and X is the amount of years.
Which question are you talking about 1 or 2?
Well, that would be 4 tables to fit 20 people but would not be enough for 2 more people so I would say 5 tables total.
-Hope this helps.
