Answer:
The answer to your question is We got the same. I think your work is correct.
Step-by-step explanation:
Data
height = 4x - 5
length = 3x + 1
width = 2x - 3
Formula
Volume of a rectangular prism = height x length x width
-Substitution
Volume = (4x - 5)(3x + 1) (2x - 3)
-Simplification
Volume = (12x² + 4x - 15x - 5)(2x - 3)
Volume = (12x² - 11x - 5)(2x - 3)
Volume = 24x³ - 22x² - 10x - 36x² + 33x + 15
Volume = 24x³ - 58x² + 23x + 15
2.- Number of computers N(t) = 5t + 106
Price of computers P(t) = 13t² + 25t + 600
Initial year = 2005
Final year = 2010
Number of years = 2010 - 2005
= 5 years
a) Calculate the numbers of computers
N(5) = 5(5) + 106
= 25 + 106
= 131 computers
b) Calculate the price
P(5) = 13(5)² - 25(5) + 600
= 13(25) - 125 + 600
= 325 - 125 + 600
= $800
c) Calculate the revenue
Revenue = 131 x $800
= $104880
