## What happens when the Saturday variable cost rises?

A fictional extension of the session case. Friday still earns $12 contribution per customer, but Saturday now costs $8 per customer rather than $6.

### Revised assumptions

| Input | Value |
| --- | --- |
| Saturday ticket | $18 |
| Saturday variable cost | $8 per customer |
| Additional Saturday fixed cost | $480 |
| Saturday customers | 50 |
| Customers displaced from Friday | 10; no replacements |
| Friday contribution per displaced customer | $12 |

## Your turn

Find the Saturday-only result and the change across the business. How many Saturday customers cover the cost if exactly ten continue to be displaced from Friday?

## For your own application
