"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that
a = kb
We're given that a = 18 and b = 3, so that
18 = 3k ⇒ k = 6
Then when b = 5, we would have
a = 6 × 5 = 30

Domestic Stamps: 60
Foreign Stamps: 36
Step-by-step explanation:
96 - 24 = 72
72 ÷ 2 = 36
36 + 24 = 60
d - f = 24
60 - 36 = 24
24 = 24
d + f = 96
60 + 36 = 96
96 = 96
