I'm pretty sure when you graph the lines, both of them meet at 5.
The solution to the system is where the lines intercept. If you look at the graph, you see that the lines intercept at (1,2). So, the answer would be C.
Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
