Using proportions, we have that:

1. The equation is: d = 0.15p.

2. The discount is of £12.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

In this problem, the discount d is 15% of the price p, hence the equation is:

d = 0.15p.

For a price of £80, the discount is given by:

d = 0.15 x 80 = £12.
