Zayna deposited $⁢1,500 into a savings account with a 4% interest that compounds annually. She wants to know how much her investment will grow after 10 years. Which formula is correct?

Use the compound-interest formula A = P(1 + r/n)^(nt), where P = 1500, r = 0.04, t = 10, and n = 1 because interest compounds annually. Substituting gives A = 1500(1 + 0.04/1)^(1×10), which matches choice B, the formula with a 4% annual rate compounded once each year for 10 years.
