Translate the sentence to an algebraic inequality.
-Suppose that the sales of a particular brand of appliance satisfy the relationship $S ( x ) = 120 x + 1600$, where $S ( x )$ represents the number of sales in year $x$, with $x = 0$ corresponding to 1990 . For what years will sales be between 1960 and 2320 ?
A) Between 1992 and 1995
B) Between 1993 and 1996
C) Between 1993 and 1995
D) Between 4 and 7

To find the years when sales are between 1960 and 2320, solve the inequality: $1960 < 120x + 1600 < 2320$. Solving gives $3 < x < 6$, corresponding to the years 1993 to 1996.
