Answer:
The correct statement is A. The account balance will increase 4% each year.
Step-by-step explanation:
Let's recall that 1.04 is the result of adding:
1 + 0.04 and, we can also write 0.04 as 4/100 or 4%,
in consequence,
1.04 = 1 + 4%, where we're increasing an additional 4%.
The correct statement is A. The account balance will increase 4% each year.
