When Owen left his house in the morning, his cell phone battery was partially charged. Let BB represent the charge remaining in Owen's battery, as a percentage, tt hours since Owen left his house. A graph of BB is shown below. Write an equation for BB then state the xx-intercept of the graph and determine its interpretation in the context of the problem.

B=40-8t

Step by step explanation:
Given that:
Rate at which battery life discharged=8% per hour;
Battery life left after 3 hours=16%
T= hours after Lucy left house

Equation B will be;
Amount of charge before leaving home-( discharge rate * number hours)

Amount of charge before leaving home:
Charge left after 3 hours + discharge rate *3
16%+8*3
16%+24%=40%

Hence,
B=40-8t
