Given

the life expectancy of a circulating coin is 30 years

the life expectancy of a circulating dollar bill is only 1/20 as long.

Procedure

c=life expectancy of a circulating coin

p= life expectancy of circulating paper money

$p=\frac{1}{20}\cdot c$ $\begin{gathered} p=\frac{1}{20}\cdot30 \\ p=\frac{30}{20} \\ p=1.5 \end{gathered}$

The answer is: life expectancy of a dollar bill = 1.5 years
