Answer:
P = 
Step-by-step explanation:
given P is inversely proportional to V then the equation relating them is
P = 
to find k use the condition when V = 8 , P = 5 , then
5 = 
( multiply both sides by 8 to clear the fraction )
40 = k
P = ← equation of proportion
Using the distributive property it would be 4(8+5) which is the same as (4×8) + (4×5)
