Answer 1

6 years

Explanation:

if we want to know how much i will get with interest

simple interest amount = principal amount × (rate / m) × n

plus the initial quantity

where m is 12 months per year

and n is the number of months

`4451=2887((0.09)/(12months/year))(n)+2887\\\\4451=2887[(0.09)/(12)(n)+1]\\\\((0.09)/(12)\cdot n)+1=(4451)/(2887)\\\\(0.09)/(12)\cdot n=1.54-1\\\\n(0.09)=12(0.54)\\\\n=(12(0.54))/(0.09)\\\\n=72.23\longleftarrow months`

so we need to convert it to years

`72.23=12(6)+0.019`

6 years and 0 months
