a) 3% of $500 is 500×0.03=$15. This means that for one year, the interest added is $15. As we are dealing with simple interest, this amount will be added on the loan each year, and doesn't change. Therefore, over 2 years, the amount of interest you pay on the loan is 15×2=$30
b) You now need to add the extra interest to the original loan. So, 500+30=$530
