Answer
Explanation:
Step1: Calculate CD interest
Use simple - interest formula $I = Prt$. Here, $P = 2680$, $r=0.07$, $t = 1$. So $I_{CD}=2680\times0.07\times1=187.6$.
Step2: Calculate savings account interest
Using $I = Prt$ with $P = 3060$, $r = 0.045$, $t = 1$. So $I_{savings}=3060\times0.045\times1 = 137.7$.
Step3: Find the difference
Subtract the savings - account interest from the CD interest: $I_{difference}=I_{CD}-I_{savings}=187.6 - 137.7=49.9$.
Answer:
B. $49.90$
