Respuesta :
Based on the price that Robin bought the watch and the price he sells it, his percentage loss is 30%.
How much loss did Robin incur?
This can be found by the formula:
= (Selling price - Purchase price) / Purchase price x 100%
Solving gives:
= (56 - 80) / 80 x 100%
= 24 / 80 x 100%
= 30%
In conclusion, Robin suffered a 30% loss.
