On Chatty Cathy’s cell phone plan she pays for minutes used plus a fixed monthly charge. For 500 minutes she pays $35 total, and

Strike441 [17]

Answer:

$25

Step-by-step explanation:

500 mins = $35 (fixed + per minute charge)

1500 mins = $55 (fixed + per minute charge)

If we let per minute charge be "m"

and

let fixed charge be "f"

we can write 2 equations as:

35 = 500m + f

and

55 = 1500m + f

Now,

We re-write both equations in terms of f and equate both expressions:

f = 35 - 500m

and

f = 55 - 1500m

Equating:

35 - 500m = 55 - 1500m

-500m + 1500m = 55 - 35

1000m = 20

m = 20/1000

m = 0.02

Now we find f, what we are looking for:

f = 35 - 500m

f = 35 - 500(0.02)

f = 25

So, the fixed charge is $25

The value of his investment at the third year is
F (3)=300×(1.02)^(3)=318.36

The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22

The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year

Can you explain to me the answers in a and b?

a. The constant of proportionality is k = 2

b. If Micah saves $150, his parents will give him $300

<h2>Explanation:</h2>

From mathematics, we know that $y$ varies directly as $x$ or $y$ is directly proportional to $x$ if and only if:

$y=kx$ for some nonzero constant $k$ .

Here we know some facts:

For every $5 that Micah saves, his parents give him $10.

In other words:

Let y be the money his parents give him.

Let x be the money that Micah saves.

$We \ know \ that: \\ y=kx \\ \\ \\ Solving \ for \ k: \\ \\ k=\frac{y}{x} \\ \\ k=\frac{10}{5} \\ \\ \boxed{k=2}$

So,<em> the constant of proportionality is k = 2</em>

In this case, we know that Micah saves $150. So we need to find the amount of his parents will give him. So what we know here is the value of x, because x represents the amount of money Micah saves. Therefore, by knowing x and k, we can calculate the value of y, which is the amount of money his parents will give him. Hence:

$For \ x=150 \ and \ k=2: \\ \\ y=2(150) \\ \\ \boxed{y=300}$

Finally, <em>if Micah saves $150, his parents will give him 300$</em>
