-The current $I$ in an electrical conductor varies inversely as the resistance $R$ of the conductor. The current is 6 amperes when the resistance is 894 ohms. What is the current when the resistance is 736 ohms?
A) $4.9 \mathrm{amps}$
B) $0.14 \mathrm{amps}$
C) $0.2 \mathrm{amps}$
D) $7.3 \mathrm{amps}$

The relationship between current $I$ and resistance $R$ is given by $I = k/R$, where $k$ is a constant. Given $I = 6$ amps when $R = 894$ ohms, we can find $k = I \times R = 6 \times 894$. When $R = 736$ ohms, the current $I = k / 736$. Substituting the value of $k$ from the first condition gives $I = (6 \times 894) / 736$, which calculates to approximately $7.3$ amps.
