The class spends $1436.4 per year on pizza. Since the population grows x² in one year, the strength of the class on the last day of the year is 12² = 144.
<h3>How to find the total population of the class in one year?</h3>
It is given that,
The current population of the classroom is 12. I.e., x = 12
So, at the end of the year, the population of the class = x²
⇒ 12² = 144
Thus, the population of the classroom on the end day of the year is 144.
<h3>How many slices of pizza are required for this population in the class?</h3>
It is given that,
On the last day of the year, each person in the classroom eats 3 slices of pizza.
So, 144 persons eat,
144 × 3 = 432 slices of pizza
Thus, 432 slices of pizza are required for the given population.
<h3>How much money does a class spend per year on pizza?</h3>
It is given that,
A single pizza has 8 slices and every single pizza costs $26.60.
Since there are 432 slices, then the number of pizzas
= 432/8
= 54 pizzas
Then, the cost of 54 pizza's = 54 × $26.60 = $1436.4
Therefore, $1436.4 was spent on pizza per year.
