4.4/20=0.22 per item
4.8/24=0.2 per item
Answer: 24 for 4.80
Answer:
9.54545454545
Step-by-step explanation:
Quotient means the answer when you divided something so I'm assuming you meant divide 315 by 33.
6 half dollar coins would= $3.00 so you would add $3.00+$3.00=$6.00
The slope is -1/4 and the y intercept it -6
A function

is periodic if there is some constant

such that

for all

in the domain of

. Then

is the "period" of

.
Example:
If

, then we have

, and so

is periodic with period

.
It gets a bit more complicated for a function like yours. We're looking for

such that

Expanding on the left, you have

and

It follows that the following must be satisfied:

The first two equations are satisfied whenever

, or more generally, when

and

(i.e. any multiple of 4).
The second two are satisfied whenever

, and more generally when

with

(any multiple of 10/7).
It then follows that all four equations will be satisfied whenever the two sets above intersect. This happens when

is any common multiple of 4 and 10/7. The least positive one would be 20, which means the period for your function is 20.
Let's verify:


More generally, it can be shown that

is periodic with period

.
