Hello! so, 0.04 rate is 4% interest. 100 * 4% (0.04) is 4. that's $4 earned each year. if terrance wants to earn $100 in interest, then in order to find out how long he needs to leave money in the account, we need to divide the amount of interest by the amount earned each year. $100 is interest and $4 is the annual amount earned. 100/4 is 25. there. terrance will need to leave his money in the account for 25 years. the answer is a: 25 years.
