Final answer:
Girma did not make a profit; he broke even. His total cost and total sales revenue were both 900 birr, resulting in a profit percent of 0%.
Step-by-step explanation:
To determine if Girma made a profit, we need to compare the total cost of the eggs to the total sales revenue. First, let's calculate the total sales revenue:
Total sales revenue = Number of eggs sold × Selling price per egg
Total sales revenue = 300 eggs × 3 birr/egg
Total sales revenue = 900 birr
Now, let's compare the total cost to the total sales revenue:
Total cost = 900 birr
Total sales revenue = 900 birr
Since total sales revenue equals the total cost, Girma did not make a profit or a loss; he broke even.
The profit percent would be calculated as follows if there was a profit:
Profit percent = (Profit ÷ Total cost) × 100%
However, since there is no profit, the profit percent is 0%.
