Pamphlets weigh 40 ounces each. each pamphlet weighs 4 ounces.

Question

What function would represent the relationship between the number of pamphlets in the box and the total mailing weight?

How would I graph the function?

How would I explain the role that the weight of the box and the weight of each pamphlet play in the graph in terms of slope and intercept?

 

Answer 1

Is this supposed to say:

Pamphlet BOXES weigh 40 ounces,
each pamphlet weighs 4 ounces.

weight as a function of # pamphlets:
w(p) = 4p + 40

The slope is 4 be ause for each rise of 1
in number of pamphlets the weight goes
up by 4 ounces.

The intercept is (0, 40) because an empty
box weighs 40 ounces.

This is a linear function. To graph just pick
a number of pamphlets, p, and solve for the
value of w(p)

p | w(p)
--------------
0 | 40
1 | 44
2 | 48

I would label the horizontal
axis as # pamphlets and label
it in units of 1.
0, 1, 2, 3, ...

I would label the vertical axis as
weight in ounces and label it in units
of 10.
0, 10, 20, 30, 40, ...
