Step-by-step explanation:
Compounding increases the principal amount or the invested amount. Scott invested $3000, which earns 12% compound interest every six months. After every six months, the interest earned will be added to the amount invested, meaning the investment will be more than $3000.
After the lapse of the 'second' six months, the interest earned with be added to the new invested amount. Therefore, at the end of the first year, the $3000 invested will be compounded or increased twice.
