Answer:

P = 0.75

Step-by-step explanation:

Given that P varies directly as I then the equation relating thenm is

P = kI ← k is the constant of variation

To find k use the condition P = 0.5 when I = 4, thus

k = $\frac{P}{I}$ = $\frac{0.5}{4}$ = 0.125

P = 0.125I ← equation of variation

When I = 6, then

P = 0.125 × 6 = 0.75
