With ( P = 1000 ), ( r = 0.05 ) (5%), and ( t = 3 ) years, the calculation becomes:", "[\nA = 1000 \left(1 + \frac{0.05}{1}\right)^{1 \ imes 3}\n]\n[\nA = 1000 \left(1.05\right)^3\n]\n[\nA = 1000 \ imes 1.157625\n]\n[\nA = 1157.63\n]", "### Result After 3 Years", "After 3 years, a $1,000 deposit earning 5% annual interest compounded annually will grow to approximately $1,157.63.
