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 :)
