"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

Step-by-step explanation:
Since she has a 30% coupon, the new price of the jeans will be 30% of the original price subtracted from the original price
Original price = $60
Therefore
30% of $60
Make 30% a decimal
30/100 x $60
0.3 x $60 = $18
New price = $60 - $18
= $42
The new price for the jeans is $42
