Answer:
c = 12 * t
Explanation:
The only equation that relates t and c would be the following...
c = 12 * t
This is because the total number of cubes that exist depends on how many available trays exist. Therefore, creating a positive correlation relationship between these two variables. Since each tray contains 12 cubes, 12 is therefore multiplied by the number of trays to get the total number of cubes. This means that the more trays available the more cubes that are created.
