Answer:

b. v = 25n

c. v = 250

d. Independent variable: n

dependent variable: v

Explanation:

Part a.

The value, v, of your quarter is a function of n, the number of quarters you have, so given a value of n, you can calculate the value of v.

If n = 1

v = 25

Because one quarter has a value of 25 cents.

If n = 2

v = 2(25) = 50

because two quartes has a value of 50 cents.

If n = 3

v = 3(25) = 75

Therefore, we can draw a diagram using the points (1, 25), (2, 50), and (3, 75) as follows

Part b.

Then, we can see that the value of your quartes is 25 times the number of quartes, so the equation that represents this function is

v = 25n

Part c.

To find the output when the input is 10, we need to replace n by 10 on the equation above

v = 25n

v = 25(10)

v = 250

So, the output is 250 cents

Part d.

The value of your quarters depends on the number of quarters you have, so the dependent variable is v, the value of your quarters and the independent variable is n, the number of quarters.
