Ответ:
Therefore it will take 28 years.
Step-by-step explanation:
To find the years, we use the following formula,
A= Total balance after n years
P= Initial amount.
r= Rate of interest per year.
n = Time in years.
Given that, Josh's grandparents put $3,000 into a college saving account when he was born. The account earn 6% interest per years.
Here A=$15,000,P=$3,000, r=6%=0.06 ,n=?
Taking ln both sides
Therefore it will take 28 years.
