Answer to Question 1

If revenue and cost schedules are calculated:
a. 6; b. 680; c. 15; d. 4500; e. 8; f. 3520

If results are calculated with equations:
a. 6.286; b. 682.86; c. 15; d. 4500; e. 8; f. 3520

Answer to Question 2

a. 52,600
b. The equation is based on data from 2000-2010. The further away from the final year, the less likely the equation is to be correct, as more factors may alter the trend seen in the data. A further issue is that the model is based on only 11 observed values.
