Question

A movie theater sells 3 sizes of popcorn as described in the table. Small=$2 Medium=$3 Large=$4 a.)Write a polynomial with 3 terms represent the total sales in dollars of all popcorn. Define the variables you use. b.) Pam says that the expression 9p represents the total number of all sizes of popcorn sold.

Answer 1

To answer this item, we let the number of small, medium, and large popcorns sold be equal to x, y, and z such that the total amount that can be obtained from the sales is,
2x + 3y + 4z = total sales
If the 9p is the total number of popcorns sold, the equation is,
x + y + z = 9p
