I need some step by step help with this one! Thank you!?
George Lucas pioneered the use of digital movie cameras with the most recent Star Wars film. Assume that Lucas’s camera has a swappable 80 GB hard drive (remember: 1 GB = 1024 MB, 1 MB = 1024 KB, 1 KB = 1024 Bytes, and 1 Byte = 8 bits), that it records each pixel in x-bit color, that there are 26 frames recorded per second, and that each frame is recorded in 1600×1200 resolution.
Create a polynomial function that gives the number of minutes of video that can be recorded before swapping in a new hard drive, as a function of x (the number of bits used to encode the color of each pixel)
Evaluate this function for x = 32 (32-bit true color)

Total capacity in bits:
C = 80 (1024*1024*1024) * 8 = 687194767360
# of bits per frame:
F = 1600*1200 * x (where x= # of bits per pixel)
= 1920000 * x
Total # of frames that can be stored on 80GB:
T = C/F
T = 357913.9413/x
At 32 bits per pixel x = 32 so:
T = 357913.9413 / 32 = 11184 frames
26 frames per second = 26 * 60 frames per minute
= 1560
Capacity in # of minutes = 11184/1560 = 7minutes
