To determine the amount of money Alex and April start with, let's examine the information provided.
First, take a look at Alex's equation:
[tex]\[ y = 20x + 125 \][/tex]
In this equation:
- [tex]\( y \)[/tex] is the total amount of money Alex has saved at the end of each week.
- [tex]\( x \)[/tex] is the number of weeks.
- The constant term, 125, represents Alex's starting amount of money.
So, Alex starts with [tex]$125.
Now, considering April's case, we don't have a specific numerical value or an equation provided for April's starting amount. Without this information, it is impossible to determine the exact amount April starts with compared to Alex.
Since the statement requires us to complete it, and we can only determine Alex's starting amount but April's remains unspecified, the correct answer for April's starting amount would be left indeterminate based on the given data.
Therefore, the complete statement would be:
"Alex starts with $[/tex]125 and April starts with [tex]$\$[/tex]$ ______."
To fill in the blank, without additional data, it is safest to state that April's starting amount is unknown.
