Question

Last year phone model at a battery not lasted 15 hours this year the battery only left it for 11.4 hours what was the percent the battery life decreased it

​

Answer 1

To find the percent decrease in battery life, subtract the new battery life from the old battery life, divide that by the old battery life, and multiply by 100.

Step-by-step explanation:

To find the percent decrease in battery life, we need to calculate the difference between the old battery life and the new battery life, and then divide that difference by the original battery life.

Percent Decrease = ((Old Value - New Value) / Old Value) * 100

Using the given information, Old Value = 15 hours and New Value

= 11.4 hours.

Plugging these values into the formula, we have:

Percent Decrease = ((15 - 11.4) / 15) * 100

= (3.6 / 15) * 100

= 24%

Therefore, the battery life decreased by 24%.
