Question

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 9.54% 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 1.908 hours of battery life in a day?
A. Phone A
B. Phone B
C. Phone C
D. Phone D
PLEASE help :)

Answer 1

Change 9.54% into a decimal to make it 0.0954. You can take this and multiply it by the battery life.

Answer 2

You can try that with the answers until you get 1.908 :)

Answer 3

let the battery life = X
then 9.54% of X = 1.908
solve for X
