Suppose the expression shown represents how much a bakery charges for a carrot cake. the total charge consists of a base price and an additional charge, where p is each additional serving beyond 8 servings. give an interpretation for the three parts of the expression. $15 + $2p

$15: base charge
p: number of extra servings beyond 8
$2: extra cherge per serving of each serving beyond 8

Explanation:
The given expression is:
Total charge = $15 + $2p

We know that the charge consists of:
1- base price (independent of any variable)
2- additional charge for beyond 8 servings (dependent on the number of servings beyond 8)

Now, for the given expression:
$15 : this term is independent of any variable. Therefore, this term represents the base price
$2p: this term is dependent on the variable p. We can infer that:
p is the number of extra serving beyond 8 servings
$2 is the extra charge for each serving beyond the 8 servings

Hope this helps :)

The perimeter of a rectangle doesn't tell you its dimensions, so there are
an infinite number of different dimensions and different areas it could have
with the same perimeter.  I'm pretty sure there's some more information in
the part of the question that you skipped over before you started copying
the part that you posted.
