how do you get that?

I think its a linear regression problem... where the data is used to find the line of best fit

anonymous · Answer

I don't understand linear regression, how do I even go about doing this problem?

campbell_st · Answer

the equation that gives the closest answer is the last one. the 2 middle equations would  give negative budgets, 

which means the answer is either the 1st or last... 

substituting some data from the table, say 1995, where x = 5  (5 years after 1990)

would give a value way below. 

so as a best guess... I'd say the last equation
