The population of classroom grows x squared in one year. the current population of classroom is 12. in one year. one the las day

Iteru [2.4K]

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.

A= P(1+rt) is used to find the principal amount p deposited, earning r% interest, for t years. Use this to find what principal a

myrzilka [38]

We have been given the formula

$A= P(1+rt)$

Now, we have been given that

$r=0.03, t=20,A=\$ 8,000$

On substituting these values in the given formula, we get

$8000=P(1+0.03\cdot 20)\\
\\
8000=P(1+0.60)\\
\\
8000= 1.60P\\
\\
P=\frac{8000}{1.60}\\
\\
P=\$5000$

David will invest a principle amount of $5000

The value, V(m), of a comic book m months after publication has an average rate of change of –0.04 between m = 36 and m = 60. Wh

german

Answer:

C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

The average rate of change for the function f(x) from $x_1=a$ and $x_2=b$ is

$\dfrac{f(b)-f(a)}{b-a}$

It is a measure of how much the function changed per unit, on average, over that interval.

Actually, this is the slope of the line passing through two points on the graph of the function.

If the average rate of change of the function f(x) between m = 36 and m = 60 is -0,04, it means that the value of the comic book decreased (because of negative number -0.04) by an average of $0.04 each month (a unit in this case is a month) between m = 36 and m = 60.
