The cost of fighting crime in the United States increased steadily in the period 1982-1999. Total spending on police and courts can be approximated, respectively, by P(t)=1.745t+29.84 billion dollars $(2 \leq t \leq 19)$ C(t)=1.097t+10.65 billion dollars $(2 \leq t \leq 19)$ where t is time in years since 1980. Compute $\lim _{t \rightarrow+\infty} \frac{P(t)}{C(t)}$ to two decimal places and interpret the result.
