Question

The proportional relationship between the total number of minutes, m, that Aaron practices the piano after some number of days, d, can be represented by the equation 29d. At what rate did he practice, in minutes per day? m

Answer 1

We can find the practice rate in minutes per day if we set d=1, and use that value to find the total minutes of practice of one day:

$\begin{gathered} m=29d \\ d=1\Rightarrow m=29 \end{gathered}$

Therefore, the practice rate is 29 minutes per day.
