Explanation :
To determine the cost of 12 eggs, we can set up a proportion. Let the cost of 12 eggs be represented by x.
We can set up the following proportion:
4 eggs / 2.75 = 12 eggs / x
To find x, we can cross multiply and then solve for x:
4 * x = 12 * 2.75
4x = 33
Dividing both sides by 4:
x = 8.25
Therefore, the cost of 12 eggs will be $8.25.
