George has opened a new store and he is monitoring its success closely.
Over [174]

Answer:

(r - c)(4) means "The new store will have a profit of $4500 after its fourth month in business" ⇒ 3rd answer

Step-by-step explanation:

George has opened a new store and he is monitoring its success closely

He has found that:

  • Store’s revenue each month can be modeled by r(x) = x² + 6x + 10 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars
  • His expenses each month can be modeled by c(x) = x² - 4x + 5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars

∵ r(x) = x² + 6x + 10

∵ r(x) is the revenue

∵ c(x) = x² - 4x + 5

∵ c(x) is the expenses

- The profit is the difference between the revenue and the

   expenses

∴ The profit = r(x) - c(x)

∵ r(x) - c(x) can me written as (r - c)(x)

∴ The profit = (r - c)(x)

∴ The profit = (x² + 6x + 10) - (x² - 4x + 5)

- Remember (-)(-) = (+) and (-)(+) = (-)

∴ The profit = x² + 6x + 10 - x² + 4x - 5

- Add the like terms

∴ The profit = (x² - x²) + (6x + 4x) + (10 - 5)

∴ The profit = 10x + 5

∴ (r - c)(x) = 10x + 5

- Substitute x by 4

∵ x = 4 ⇒ 4 months

∴ (r - c)(4) = 10(4) + 5

∴ (r - c)(4) = 45

∵ r and c are in hundred dollars

∴ The profit = $4500

(r - c)(4) means "The new store will have a profit of $4500 after its fourth month in business"
