20%= .2
36*.2= 7.2
36+ 7.2= 43.20
$43.20 was the original price of the jacket.
I hope this helps!

There really aren't any steps. It's just a handy fact about Isosceles triangles.
An Isosceles triangle is a triangle that has two sides that are the same length,
and one of the facts about this kind of triangle is that the angles opposite the
two equal sides are equal angles.
In your picture, the two sides of the triangle that have tick marks across them
are equal lengths, and that means that the angles at 'S' and 'U' are equal angles.
In this kind of triangle, those are called the "base angles", even though they
don't necessarily have to be the angles that the triangle stands on. They're
just the two angles that are opposite the two equal sides.
We can represent each company's graph by the following equations
V = (0.04)*H...............(Company P)
V = (0.06)*H...............(Company S)
(V represents the vacation hours and H the hours worked)
If both work 2080 hours
V1 = (0.04)*(2080) = 83.2 vacation hours..............(Company P)
V2 = (0.06)*(2080) = 124.8 vacation hours ..............(Company S)
124.8 - 83.2 = 41.6 hours
The friend at company S will have about 42 more vacation hours that the friend at company P
