Inverse and Direct Variation Word Problems - Examples

Ohm's law is a law in circuits that states the voltage $V$ across a resistor $R$ is related to the current $I$ by the equation $V=IR$. If a resistor of $3$ ohms has a current through it and that creates a Voltage of $24$ Volts across the resistor, how many volts would go across the resistor if we replaced it with an $8$ ohm resistor and kept the same current?
