Respuesta :
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.
How to find the total population of the class in one year?
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.
How many slices of pizza are required for this population in the class?
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.
How much money does a class spend per year on pizza?
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.
