Suppose you invest $2250 in a D that earns 3% APR and is compounded monthly. The Cd matures in 2 years. How much will this CD be

olasank [31]

Answer:

$2388.95

Step-by-step explanation:

Principal, P= $2250
Annual Interest Rate, r= 3% =0.03
Time, n= 2 years
Since it is compounded monthly, Period, k= 12 Months

The worth of a compound deposit after a period of n years is calculated using the formula:

$A(n)=P(1+\frac{r}{k})^{nk}$

$A(2)=2250(1+\frac{0.03}{12})^{12 \times 2}\\\\=2250(1+0.0025)^{24}\\=2250(1.0025)^{24}\\=\$2388.95$

At maturity, the deposit will be worth $2388.95.
