Answer 1

The difference between simple and compound interest is significant because the interest is higher when using compounding. Robert's investment amounted to $12,000 after 4 years while Rosie's investment after 4 years totaled to $13,117.55 with a difference of $1,117.55.

Thus, Rosie will have $1,117.55 more than Robert.
