Answer:
1.75 years or 1 year and 9 months.
Step-by-step explanation:
We have been given that the life expectancy of a circulating coin is 35 years. The life expectancy of a circulating dollar bill is only 1/20 as long.
To find the life expectancy of circulating paper money, we need to calculate 1/20 of 35 years.
[tex]\text{Life expectancy of circulating paper money}=35\text{ years}\times \frac{1}{20}[/tex]
[tex]\text{Life expectancy of circulating paper money}=1.75\text{ years}[/tex]
[tex]0.75\text{ year}=0.75\times\frac{\text{12 months}}{\text{year}}=\text{9 months}[/tex]
Therefore, the life expectancy of circulating paper money is 1.75 years or 1 year and 9 months.
