I'm not sure what the question is referring to as "table value", but this is solved using simple interest calculation (no compounding). I have left the structure of the solution without solving the entire problem, so that you can learn the fomula, etc.
Beginning Date 5/15/2010
Ending Date 10/13/2010
Days in lending period 148
Days in year 360
Percentage of year in lending period (solve for this)
Principal amount 703,000
x Rate, annual (provided in question)
x Percentage of year (from above answer)
Product of above (interest due at maturity)
(solve for this) A
Add: Principal amount due at maturity 703,000 B
Total due at maturity (solve for this) A + B
Remember: interest due = principal amount X rate (annual) X time (percentage of year that loan is outstanding). Don't forget to add back in the principal amount due at maturity, as well.
