Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.

The marginal revenue of selling the eighth unit is $-4.
A monopolist is the only producer in the industry. A monopolist operates in a monopoly. The monopolist sets the market price of their products.
Marginal revenue is the change in total revenue when quantity sold increases by one unit.
Marginal revenue = change in total revenue / change in quantity sold
change in total revenue = ($3 x 8) - ($4 x 7) = $-4
change in quantity sold = 8 - 7 = 1
Marginal revenue = $-4 / 1 = $4
