Answer:
Alex starts with 125 and April starts with 100.
Explanation:
Since Alex wrote an equation to show the total, y, she has saved at the end of each week, x.
[tex]y = 20x + 125[/tex]
In order to find the starting amount of Alex, we need to put x = 0
Therefore we would get,
[tex]y = 125[/tex]
Thus, Alex's starting amount was 125.
And since April made a graph with x = 0, and 7 = 100, this would make April's starting amount is 100.
Hense, Alex's savings amount is greater than April's.
[tex]125>100[/tex]
