Solve the problem.
-The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 7 amperes when the resistance is 765 ohms. What is the current when the resistance is 777
Ohms?
A)0.15 amp
B)0.14 amp
C)6.9 amp
D)7.1 amp

The relationship between current (I) and resistance (R) is given by I = k/R, where k is a constant. For the initial condition, 7 = k/765, so k = 7 * 765. For a resistance of 777 ohms, I = (7 * 765) / 777 = 6.9 amperes.
