When Isabella left her house in the morning, her cell phone battery was partially charged. Let B represent the charge remaining in Isabella's battery, as a percentage,
t hours since Isabella left her house. The table below has select values showing the
linear relationship between t and B. Determine the percentage charge that Isabella's
phone loses each hour.

answer is 33

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
