Answer: d. $7,463.77
Explanation:
The formula to calculate the simple interest is given by :-
, where P is the principal amount , r is the rate of interest ( in decimal) and t is time ( in years). (1)
Given : Nate has an account that pays 2.76% simple interest per year and wants to accumulate $3,090 in interest from it over the next 15 years.
i.e. I= $3,090 ; r= 2.76% =0.0276 and t= 15 years
Then, from (1), we have

Hence, the amount of money Nate should invest in this account to meet this goal = $7,463.77
