Hi Franziska,
This is a classic breakeven!
So, first, create the full formula, and then pulg-in what's missing.
- Profit from warranty* % quantity sold = Profit loss from car
- (Revenue from warranty - expected cost from warranty) * quantity sold = Profit loss from car
- (2,350 - 1,100) * quantity sold = $1,000
- 1,250 * quantity sold = $1,000
- Quantity sold = 1,000/1,250 = 80%
