Step-by-step explanation: 60/300 is the same as 30/100 so it is 30%
The error is that 15 was subtracted on the left side when it should’ve been added.

Step-by-step explanation:
Answer:
Actually, the equation is
power (in Watts) = I² * r
I - current in amps and r - resistance in watts
Solving this for the current (I)
I = square root (power / resistance)
I = square root (15 / 100)
I = square root (.15)
I = 0.3872983346 amps
answer is B
