A data analyst for a phone company is analyzing the data of 150 of their customers, which accounts for 1% of their total customers. The analyst wants to determine the average number of hours each day a customer uses their phone, for calls and for texts, during a 30-day period. Based on the data, the customers averaged 0.25 hours per day per call and 1.75 hours each day for texts. Construct an equation in the correct form of y=mx+b to represent this situation. Let t represent the number of calls made per day, and e represent the total number of hours a customer uses their phone each day.
The average number of hours a customer uses their phone each day can be represented as the sum of the hours spent on calls and the hours spent on texts, so we can write:
e = t(0.25) + (1.75)
Or simplifying:
e = 0.25t + 1.75
This equation represents the situation, where e represents the total number of hours a customer uses their phone each day and t represents the number of calls made per day.
