The Number of Visitors, in Millions of Visitors Per Year $n ( t ) = - 0.068 t ^ { 2 } + 0.572 t + 4.39$

Multiple Choice

The number of visitors, in millions of visitors per year, to Hawaii in the years 1985 to 1993 can be approximated by
$n ( t ) = - 0.068 t ^ { 2 } + 0.572 t + 4.39$
Where $t = 0$ represents June 30,1985. During the same period, visitor spending can be approximated by
$r ( t ) = - 0.453 t ^ { 2 } + 5.6 t + 6.65$
Where $t = 0$ represents June 30,1985. Assuming the trends in the models above continue indefinitely, numerically estimate $\lim _ { t \rightarrow + \infty } \frac { r ( t ) } { n ( t ) }$ .

Please round the answers to the nearest hundredth.

A) $\lim _ { t \rightarrow + \infty } \frac { r ( t ) } { n ( t ) } = 5.21$
B) $\lim _ { t \rightarrow + \infty } \frac { r ( t ) } { n ( t ) } = 6.66$
C) $\lim _ { t \rightarrow + \infty } \frac { r ( t ) } { n ( t ) } = 8.66$
D) $\lim _ { t \rightarrow + \infty } \frac { r ( t ) } { n ( t ) } = 6.11$
E) does not exist
