For simple interest, we have this interest equation

    I = Prt


(I is the interest, P is the loan amount, r is the annual rate as a decimal and t is the time in years).


In our case this equation takes the form

    90 = 3000*0.15*d,


which implies  d =  =  =  of an year = 365/5 days = 73 days.


73 days after June, 9 is August, 21.


    //  ( I used online date calculator https://www.timeanddate.com/date/dateadded.html?d1=9&m1=6&y1=2000&   )


ANSWER.  The maturity day is  August, 21.    ANSWER

Solved.
