Answer:
t = 53d
Step-by-step explanation:
Let's denote:
Given that Colin sends 53 text messages a day, we can express the relationship between the number of days ([tex] d [/tex]) and the total number of messages sent ([tex] t [/tex]) as follows:
Each day, Colin sends 53 text messages.
Therefore, the total number of messages he sends ([tex] t [/tex]) is the product of the number of days ([tex] d [/tex]) and the number of messages he sends per day (53).
So, the equation representing the relationship is:
