Video games sold: x

Revenue function: R (x) = 60x

Cost function: C (x) = 12 + 7x

Profit function: Px) =

Profit P (x) = 53x-12 and On selling 20 video games profit will be 1048.

Step-by-step explanation:

In the given question functions are Revenue function : R (x) = 60x and Cost function : C (x) = 12+7x for the sale of x video games

As we know profit = sale price - cost price

Therefore P (x) = R (x) - C (x)

Or P (x) = (R-C) x = 60x - (12+7x)

P (x) = 60x - 12 - 7x

P (x) = 53x - 12

Now the profit on selling 20 video games will be

P (20) = 53*20 - 12 = 1060 - 12 = 1048.
