Answer: $59.40 of interest in 2 years, $719.40 in total
Step-by-step explanation:
If you would divide $660 by $100 then 1% of that amount would be $6.60. Assuming it is 4.5% from your question, if you would multiply the amount above then Luis would get $29.70 per year. Also assuming that his savings account isn't changed over time, you would multiply 2 to get $59.40 which is the total amount of interest money earned in 2 years. Add that amount to $660 and you would get $719.40 as the second part of the answer.
