The table shows the battery life of four different mobile phones:
Mobile Phone Battery Life
Phone Battery Life (hours)
A 20
B 25
C 10
D 18
If 8.45% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.69 hours of battery life in a day?

Group of answer choices
Phone B
Phone A
Phone C
Phone D
To determine which mobile phone would use a total of 1.69 hours of battery life in a day, we can calculate 8.45% of the battery life for each phone and compare the results.
For Phone A: 8.45% of 20 hours = 0.0845 * 20 = 1.69 hours
For Phone B: 8.45% of 25 hours = 0.0845 * 25 = 2.11 hours
For Phone C: 8.45% of 10 hours = 0.0845 * 10 = 0.845 hours
For Phone D: 8.45% of 18 hours = 0.0845 * 18 = 1.523 hours
Based on these calculations, the mobile phone that would use a total of 1.69 hours of battery life in a day is Phone A. Therefore, the correct answer is Phone A.
