Question

When Emma left her house in the morning, her cell phone battery was partially charged. Let BB represent the charge remaining in Emma's battery, as a percentage, tt hours since Emma left her house. The table below has select values showing the linear relationship between tt and B.B. Determine how many hours after leaving her house it would take until the phone's battery level got down to 3.5%.

Answer 1

7.5 hours

Explanation:

6-4.4=1.5

24.5-14=10.5

So, that means every hour her phone battery goes down 10.5%

To find how many hours just add 1.5 to the time and subtract 10.5 from the percentage every time until you find your answer
