The table shows the battery life of four different mobile phones: Mobile Phone Battery Life Phone Battery Life (hours)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?
A 20
B 25
C 10
D 18
To find the mobile phone that would use a total of 1.69 hours of battery life in a day, we need to multiply 8.45% (0.0845) by the battery life of each phone and check which one equals 1.69.
Let's calculate for each option:
A) 20 * 0.0845 = 1.69 --> This is a match!
B) 25 * 0.0845 = 2.1125 --> This is not a match.
C) 10 * 0.0845 = 0.845 --> This is not a match.
D) 18 * 0.0845 = 1.513 --> This is not a match.
Therefore, the mobile phone that would use a total of 1.69 hours of battery life in a day is A) 20.
