Yes it is a function :))))))))))
Let us assume the original price of the shirt = x
Let us assume the sale price of the shirt = y
20x/100 = y
x/5 = y
x = 5y
Now the second equation that we get is
x = y + 5
5y - y = 5
4y = 5
y = 5/4
Now putting the value of y in the first equation we get
x = 5y
= 5 (5/4)
= 25/4
= 6 1/4
Then we can say that the original price of the shirt was 6 1/4. The main trick of this problem lies in the words that have been used in the question. It is important to understand the question first before starting to solve the problem.

Hello from MrBillDoesMath!
Answer:
x = 140
Discussion:
Please clarify! It appears from the diagram that x + 40 = 180 (nothing to do with parallel lines). Then
x + 40 = 180 => subtract 40 from each side
x + 40 - 40 = 180 -40
x = 140
I doubt this is what was meant. I will update this answer if you provide more info.
BTW: y = 40 degrees as alternate interior angles created by a transversal cutting parallel lines are equal.
Thank you,
MrB
