9. Gregory's nine chickens laid an average of six eggs each per week. Gregory sold those eggs for $300 per dozen. How much money did he collect in two weeks if he sold all his eggs??

Step-by-step explanation:

Average in one week 6eggs

2 weeks 12 eggs

1 dozen =12 eggs

1 dozen =300 dollars

2*300=600 ans

$2,700

Step-by-step explanation:

The first thing we should do is to find the number of eggs in two weeks.

6 eggs each for 9 chickens which means:

6 * 9 = 54

54 eggs per week.

In two weeks,

54 * 2 = 108

108 eggs for two weeks

Now a dozen is equivalent to 12 eggs. So if you divide 108 to 12:

108 ÷ 12 = 9

So it is 9 dozens. Then he's selling those eggs for $300 per dozen.

300 * 9 = $2,700

That's it.
