Pregunta 113Which purchase has the lowest price per kilogram?4.80 dollars for 1.2 kilograms✓Respuesta correcta6.25 dollars for 1.25 kilograms3.60 dollars for 0.8 kilogram7.50 dollars for 1.5 kilogramsExplicaciónThe unit prices are 4.80 ÷ 1.2 = 4, 6.25 ÷ 1.25 = 5, 3.60 ÷ 0.8 = 4.5, and 7.50 ÷ 1.5 = 5 dollars per kilogram. Comparing total prices alone would wrongly favour 3.60 dollars even though its quantity is also smaller.
