Answer:
required expression for profit = 3x - 180
the profit by selling 1000 units will be $ 2820
Step-by-step explanation:
Given,
Revenue = 5x² + 2x -80
cost = 5x² - x + 100
Hence profit = Revenue - cost
=> profit = 5x² + 2x -80 - (5x² - x + 100)
=> profit = 5x² + 2x -80 - 5x² + x - 100
=> profit = 3x - 180
which is the required expression for profit.
number of video games sold = 1000
=> x = 1000
hence,
profit = 3x - 180
= 3000 - 180
= $ 2820
hence the profit by selling 1000 units will be $ 2820
