Answer:
Phythagorean Theorem - a^2 + b^2 = c^2
Step-by-step explanation:
It represents the Pythagorean Theorem because in the model there is a right triangle and you can use the phythagoren theorem with any right triangle that has at least two known sides.
Since you know all the sides in this diagram, this would be true:

Raymond's stamp collection ➞x
Alice′s stamp collection➞75%x
75%x-40%×75%x+140=x-20%x
75%x-30%x+140=80%x
45%x+140=80%x
140=80%x-45%x
x=400
Raymond′s stamp collection ➞400
Alice′s stamp collection➞300
Alice sold 300×40%=120
Answer:120
