Respuesta :
the total number of hours a customer uses his phone each day (e) = the number of hours the customer spend on calls + the number hours the customer spend on texts.
The number of hours the customer spend on calls = the number of calls the customer made per day (t) times the average time spent by custormers per day per hour (0.25 hours)
The number of hours the customer spend on texts is given as 1.75 hours each day.
Therefore required equation is:
e = 0.25t + 1.75
The number of hours the customer spend on calls = the number of calls the customer made per day (t) times the average time spent by custormers per day per hour (0.25 hours)
The number of hours the customer spend on texts is given as 1.75 hours each day.
Therefore required equation is:
e = 0.25t + 1.75
