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?

A 20

Step-by-step explanation:

Given

Phone Battery Life (hours)

A 20

B 25

C 10

D 18

8.45% of the battery life of each mobile phone is used in a day by a typical user

Calculating Hours of battery life in a day for each mobile

A 20

Battery life for A = hours

B 25

Battery life for B = hours

C 10

Battery life for C = hours

D 18

Battery life for D = hours

Therefor Mobile phone A 20  uses a total of 1.69 hours of battery life in a day

the answer to this question is yes

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
