Answer:
90 euros more
Explanation:
Let the number be x
Then,let Ivan's share be 4x and Tanya's share be x
From the given scenario, the equation to represent this would be
4x+x=150 euros
Combine the like terms so that
5x=150 euros
Divide both sides by 5 and simplify
5x/5 and 150/5
so x=30
Ivan's share is 4 times the amount of Tanya's so
4*30=120 euros
So Tanya's share is x=30 euros
Therefore, Ivan gets 90 euros more than Tanya
