Given:
First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg.
Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg.
At this point she had sold all her eggs.
To find:
The number of egg the lady have when she came to the market.
Solution:
Let x be the number of egg that the lady have when she came to the market.
First customer bought 1/2 of all eggs of lady seller and 1/2 of an egg. So, the number of remaining eggs after first customer is
Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg. So, the number of remining egg after second customer is
At this point she had sold all her eggs. It means the remining eggs is 0.
Multiply both sides by 4.
Therefore, the lady came to the market is with 3 eggs.
The answer would be 1/3. You should add up the flags, and then divide the number of desired outcomes (5) by the total number of outcomes (15). Reduce it to simpler terms when finished.
Hope that helps :)
Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21
Let the second no. be x
-3x = 21 → x = 21/-3 → x = -7
