Explanation:

Step1: Identify the relationship

Total earnings \( y \) depend on the number of cups sold \( x \) and the earnings per cup. They earn $2 per cup, so the total earnings are the number of cups times the earnings per cup.

Step2: Write the equation

Since each cup gives $2, for \( x \) cups, the total earnings \( y = 2\times x \), which is \( y = 2x \).

Answer:

\( 2x \)
