The equation that relates the number of days and number of minutes Mrs. Decker walks is m = 30d.
Step-by-step explanation:
The equation that relates the number of days d that Mrs. Decker walks and the number of minutes m that she spends walking is m = 30d.
This equation states that the number of minutes Mrs. Decker spends walking is equal to 30 multiplied by the number of days she walks.
For example, if Mrs. Decker walks for 5 days, then the number of minutes she spends walking would be 30 multiplied by 5, which is 150 minutes.
