The correct answer is:  [C]:  " $4290.00 " .
_______________________________________
Explanation:
_________________________________________
Given:  principal, "P":  equals:  $14,300  ;
                 rate, "r" : equals:  7.5 %  = 7.5 / 100 = 0.075 ; 
                time, "t" (in years): equals:  4  ;
_________________________________________
What is the interest, "i" ? 
_________________________________________
  Note:  The formula:  i = P * r * t   .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4)  ;

i = $1,490 ;  which is answer choice:  [C]:  " $4290.00 " .
