Question
Two brands of shampoo are for sale in the shop. Brand A is 350ml for €5.29 and Brand B is 700ml for €8.99. Which brand is better value?
Solution
Para determinar cuál marca de champú ofrece mejor valor, debemos calcular el costo por mililitro (ml) de cada marca y compararlos.
-
Calcular el costo por ml de la Marca A:
- Precio de la Marca A: €5.29
- Volumen de la Marca A: 350 ml
- Costo por ml de la Marca A = Precio / Volumen
- Costo por ml de la Marca A = €5.29 / 350 ml ≈ €0.0151 por ml
-
Calcular el costo por ml de la Marca B:
- Precio de la Marca B: €8.99
- Volumen de la Marca B: 700 ml
- Costo por ml de la Marca B = Precio / Volumen
- Costo por ml de la Marca B = €8.99 / 700 ml ≈ €0.0128 por ml
-
Comparar los costos por ml:
- Costo por ml de la Marca A: ≈ €0.0151
- Costo por ml de la Marca B: ≈ €0.0128
Dado que el costo por ml de la Marca B (€0.0128) es menor que el costo por ml de la Marca A (€0.0151), la Marca B ofrece mejor valor.
