Answer:
a) p = 10.20
Step-by-step explanation:
Step(i):-
Given that p varies directly as q
p ∝ q
⇒ p = k q
where 'K' is proportionally constant
given p =20.8 and q = 31.2
p = k q
⇒ 20.8 = k (31.2)
[tex]k = \frac{20.8}{31.2}[/tex]
k = 0.666
Step(ii):-
p = k q
Given that q = 15.3 and k = 0.666
p = 0.666 ×15.3 = 10.20
