From 1990 to 1997, the number of cell phone subscribers S (in thousands) in the US can be modeled by, S = 5535.33(1.413)x where ‘x’ is number of years since 1990. a ) Identify the growth factor (constant ratio) and annual percent increase
b) In what year was the number of cell phone subscribers about 31 million? How do you know?
c ) According to the model, in what year will the number of cell phone subscribers exceed 90 million? How do you know?
d ) Determine the number of subscribers in 2010. How do you know?

Which situation could best be represented by this linear equation? 24x + 38y = 520 > if x represents the number of bracelets and y represents the number of rings, there were 24 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets and y represents the number of rings, there were 38 more bracelets sold than rings. the total sales were $520. if x represents the number of bracelets sold at $24 each and y represents the number of rings sold at $38 each, the total sales were $520 if x represents the number of bracelets and y represents the number of rings, there were 520 bracelets and rings sold. bracelets were $24, and rings were $38. e
