Answer:
The cost of an egg is $0.11
Step-by-step explanation:
Given : The cost of one dozen of eggs is $ 1.35
We have to find the cost of one egg.
We know, one dozen has 12 units
Thus, One dozen of eggs contain 12 eggs
So cost of 12 eggs is $ 1.35
So to find the cost of one egg divide the cost by 12.
We get,
1 egg =
Thus, The cost of an egg is $0.11
Multiply the equation:
The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as
Multiplying this by 3 (or whatever number, for all it matters) gives
Now, a product is zero if and only if at least one of the factor is zero. So, either or
Since the first is clearly impossible, the second one must be true, which is the original equation.
