<u><em>Answer: </em></u><u><em /></u><em />$15: base charge p: number of extra servings beyond 8 $2: extra cherge per serving of each serving beyond 8<u><em>
Explanation: </em></u><u><em>The given expression is:</em></u> Total charge = $15 + $2p
<u><em>We know that the charge consists of:</em></u> 1- base price (independent of any variable) 2- additional charge for beyond 8 servings (dependent on the number of servings beyond 8)
<u>Now, for the given expression:</u> $15 : this term is independent of any variable. Therefore, this term represents the base price $2p: this term is dependent on the variable p. <u>We can infer that:</u> p is the number of extra serving beyond 8 servings $2 is the extra charge for each serving beyond the 8 servings
