The price and quantity that maximizes the company's profit will be 30 and $700 respectively.

How to calculate the price?

The price and quantity that maximizes the company's profit will be calculated thus:

MR = MC

1000 - 20Q = 100 + 10Q

20Q + 10Q = 1000 - 100

30Q = 900

Q = 900/30

Q = 30

Price = 1000 - 10Q

= 1000 - 10(30)

= 1000 - 300

= 700

The price and quantity that would maximize social welfare will be:

MR = MC

1000 - 10Q = 100 + 10Q

10Q + 10Q = 1000 - 100

20Q = 900

Q = 900/20

Q = 45

Price = 1000 - 10Q

= 1000 - 10(45)

= 1000 - 450

= 550

The dead weight loss will be:

= 1/2(45 - 30)(700 - 400)

= 1/2 × 15 × 300

= 2250

In conclusion, the increase in total cost by $2000 won't have any change on the deadweight loss.
