The constant of proportionality is 7.5
Explanation:
From: https://en.wikipedia.org/wiki/Proportionality_(mathematics)
Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that
y=kx
The relation is often denoted, using the ∝ or ~ symbol, as
and the constant ratio
In this problem k = 7.5
