Question

each pizza serves 4 people. what equation finds pizzas needed for 28 people?
$4g = 28$
$4 + g = 28$
$g + 4 = 28$
$g - 4 = 28$

Explanation:

Step1: Define the variable

Let \( q \) be the number of pizzas. Each pizza serves 4 people, so the total number of people served by \( q \) pizzas is \( 4q \).

Step2: Set up the equation

We need to serve 28 people, so the equation is \( 4q = 28 \). The other options do not represent the relationship between the number of pizzas, the number of people per pizza, and the total number of people. For example, \( 4 + q = 28 \) would imply adding 4 and the number of pizzas to get 28, which is not correct. \( q + 4 = 28 \) and \( q - 4 = 28 \) also do not represent the correct relationship.

Answer:

\( 4q = 28 \) (the first option)
