Answer:

Words for dividing:

  • shared
  • each
  • for every
  • per

The problem is asking you to divide, because the key word is, "fill empty egg cartons that each hold"

So Mary will fill  each carton with 12 eggs each until she runs out.

216 / 12

<em>12 goes into 216 eighteen times exactly.</em>

<em />12 * 18 = 216

<em>and the result is(R means leftovers, which are none here)...</em>

<em />18~R~0

Suppose an oligopoly consists of two firms. Firm A lowers price and Firm B responds by lowering its price by the same amount. If
VMariaS [17]

Answer:

The profits for firma A and B will decrease.

Step-by-step explanation:

Oligopoly by definition "is a market structure with a small number of firms, none of which can keep the others from having significant influence. The concentration ratio measures the market share of the largest firms".

If the costs remain the same for both companies and both firms decrease the prices then we will have a decrease of profits, we can see this on the figure attached.

We have an equilibrium price (let's assume X) and when we decrease a price and we have the same level of output the area below the curve would be lower and then we will have less profits for both companies.
