Answer:
He bought 72 eggs and made 18 souffles
Step-by-step explanation:
In this question, we are concerned with calculating the number of eggs bought and the number of souffles made in the restaurant
We proceed as follows;
Let the number of souffles baked be x, this means that the number of eggs bought will be 4x eggs
Now, we also can see that from the question, he uses 3 eggs per soufffle baked, this means that the total number of eggs used is 3x
Now, we have 18 eggs left. This means that the difference between the number of eggs bought and the number of eggs used in making souffles = 18
Hence, 4x - 3x = 18
⇒ x = 18
Number of eggs bought = 4x = 4(18) = 72 eggs
Number of souffles made = x = 18 souffles
