Create a math problem using the expressions [tex]25000 - 8000X[/tex] and [tex]7000 + 2000X[/tex].

Answer :

We created a math problem involving revenue and cost expressions, found the profit function, and calculated the profit for X = 2, resulting in a profit of -2000.

Problem:

You are running a business where the revenue and cost are given by the following expressions:

  1. Revenue: 25000 - 8000X
  2. Cost: 7000 + 2000X

where X is the number of units produced and sold (in thousands).

Determine the profit function and calculate the profit when X = 2.

Solution:

  1. The profit function is given by:
    Profit = Revenue - Cost
  2. Substitute the expressions for Revenue and Cost:
    Profit = (25000 - 8000X) - (7000 + 2000X)
    Profit = 25000 - 8000X - 7000 - 2000X
    = 18000 - 10000X
  3. Now, substitute X = 2:
    Profit = 18000 - 10000(2)
    Profit = 18000 - 20000
    = -2000
  4. Therefore, when X = 2, the profit is -2000.

2500-8000*7000+2000*
