Math word problem help: Sales in year x given by S(x) = 210x + 500

[FONT=&quot]I am having an issue putting this word problem together in my mind. I feel that there is not enough info to complete this problem! Any help would be greatly appreciated! [/FONT][FONT=&quot]

Suppose the sales of a particular brand of appliance satisfy the relationship S(x) = 210x + 500, where S(x) represents the number of sales in year x, with x = 0 corresponding to 1982. Find the number of sales in 1996.[/FONT]

Suppose the sales of a particular brand of appliance satisfy the relationship S(x) = 210x + 500, where S(x) represents the number of sales in year x, with x = 0 corresponding to 1982. Find the number of sales in 1996.

There is enough information.

1982 ==> 1982 - 1982 = 0 ==> S(0) = 210(0) + 500 = 000 + 500 = 500 = 1982 sales.
1983 ==> 1983 - 1982 = 1 ==> S(1) = 210(1) + 500 = 210 + 500 = 710 = 1983 sales.
etc.

The worst part is simply indexing the years.

S(x) represents the number of sales in year x, with x = 0 corresponding to 19
82. Find the number of sales in 1996.

If S(x) represents the number of sales in year x, with x = 0 corresponding to 1982, then x=1 corresponds to what year?
If S(x) represents the number of sales in year x, with x = 0 corresponding to 1982, then x=2 corresponds to what year?
If S(x) represents the number of sales in year x, with x = 0 corresponding to 1982, then x=3 corresponds to what year?
If S(x) represents the number of sales in year x, then x = ? corresponding to 1996?

Before you can do this problem you 1st need to understand what S(x) really means.
