Answer:
The proportional equation is [tex]t = 37d[/tex]
Step-by-step explanation:
Serenity practices the piano 1036 minutes in 4 weeks.
Each week has 7 days, so 4 weeks = 4*7 = 28 days.
The amount of minutes she practices per day is given by:
[tex]\frac{1036}{28} = 37[/tex]
So, after d days, the total amount of time she will have practiced is given by:
[tex]t = 37d[/tex]
