Question

1. if jennifer uses her cell phone approximately 2.5 hours a day for her new travel business monday through friday, and 2.5 hours a day for personal calls on saturdays and sundays, how many minutes will she use in april, which has 30 days? a. 2,500 minutes b. 3,000 minutes c. 3,500 minutes d. 4,500 minutes

Explanation:

Step1: Calculate the number of minutes per day for non - weekend days

There are \(30\) days in April. There are \(2\) weekend days (Saturday and Sunday) in a week. So the number of non - weekend days is \(30 - 2\times4=22\) (assuming 4 full weeks). She uses \(2.5\) hours per day for non - weekend days. Since \(1\) hour \( = 60\) minutes, \(2.5\) hours \(=2.5\times60 = 150\) minutes. The total minutes for non - weekend days is \(22\times150=3300\) minutes.

Step2: Calculate the number of minutes per day for weekend days

On weekends (Saturday and Sunday), she uses \(2.5\) hours per day for personal calls. So for \(2\times4 = 8\) weekend days (4 weeks), the total minutes for weekend days is \(8\times2.5\times60=1200\) minutes.

Step3: Calculate the total minutes

The total minutes \(T\) is the sum of the minutes for non - weekend and weekend days. \(T=3300 + 1200=3500\) minutes.

Answer:

C. 3,500 minutes
