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, B phone, C phone, and D phone

Respuesta :

Let the battery life = X then 9.54% of X = 1.908 solve for X. 9.54% is very close to 1/10. So you can estimate which of the choices comes nearest to 1.908 by finding one tenth of each choice. Then check the choice by multiplying its value by 0.0954 to see if you get 1.908. Phone B which is 25.
