The proportional equation is t = 37d

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:

$\frac{1036}{28} = 37$

So, after d days, the total amount of time she will have practiced is given by:

t = 37d
