Answer: " 1 year . "
_________________________________________________
Step-by-step explanation:
_________________________________________________
Use the formula/equation:
I = Prt ; that is; " I = P × r × t " ;
in which:
" Interest (in dollars) =
Principal amount ("P" ; in dollars) * r ["rate"] * time ("t", in years) ] ;
Note: the rate, "r" ; refers to the interest rate.
We wish to solve for the "time, "t" .
_________________________________________________
I = Prt ;
_________________________________________________
Let us isolate "t" one one side of the equation;
by rearranging the formula;
We know: I = Prt ;
Divide each side of the equation by "Pr" :
I/ (Pr) = [ (Prt) / (Pr) ] ;
to get:
I / (Pr) = t ;
↔ t = I (P * r ) ;
Now, plug in our given values, and solve for "t" ; time, in years.
Given: P = 500 (dollars) ;
I = 25 (dollars) ;
r = 5% ; Note, for the purposes of this formula; we write this as a "decimal" ;
r = 5% = 5/100 = 0.05 ;
_________________________________________________
t = I / (P * r) ;
t = 25 / (500 * 0.05) ;
t = 25 / (25) ;
t = 1 yrs.
