Answer: Hence, our required expression would be [tex]y=12-2x[/tex]
Step-by-step explanation:
Since we have given that
Amount that Mike has = $12
Amount he spends each day = $2
Let the number of days be 'x'.
Let the amount remaining at the end be 'y'.
So, According to question, it becomes,
[tex]y=12-2x[/tex]
Hence, our required expression would be [tex]y=12-2x[/tex]
