To determine the relationship between the number of napkins remaining (y) and the number of tables Akira sets (x), we can start with the total number of napkins and account for the number of napkins used per table.
- Akira starts with 85 napkins.
- She uses 6 napkins for each table she sets.
The equation that shows how the number of napkins remaining (y) depends on the number of tables (x) can be expressed as follows:
\[ y = 85 - 6x \]
Where:
- \(y\) is the number of napkins remaining,
- \(x\) is the number of tables Akira sets,
- \(85\) is the initial number of napkins,
- \(6x\) is the total number of napkins used for \(x\) tables.
