Ow much money will you need to invest initially to have $750.00 in 10 years and 8 months if the money is compounded daily at an annual rate 2 1/2%

What're u asked to find, Simple interest? i guess it SI. let me try, not sure. Principal=750.00, Time= 10.8, Rate= 2.1/2%.  
SI= PRT
       100, 
=750.OO x 2 x 10.8
       100x1/2
= 16200
      50
=   324
:; SI= 324. 
NOT REALLY SURE, BUT I GUESS IT IS.

Here, feel free to ask if there are any questions
