In Electronics, the Formula $V = I R$ Is Called Ohm's Law

In electronics, the formula $V = I R$ is called Ohm's law. It gives the relationship in a circuit between the voltage $V$ (in volts) , the current $I$ (in amperes) , and the resistance $R$ (in ohms) .
Find $\mathrm { V }$ when $I = 8 - 3 i$ amperes and $R = 6 + 8 i$ ohms.

A) $\quad V = 82$ volts
B) $\quad V = 72$ volts
C) $\quad V = i$ volts
D) $\quad V = 72 + 82 i$ volts
E) $\quad V = 72 + 46 i$ volts
