Answer:

Deberán utilizarse 195 mililitros de la marca Nº1 (260 x 0.75 = 195), y 65 mililitros de la marca Nº2 (260 x 0.25 = 65).

Step-by-step explanation:

Si se utiliza enteramente la marca Nº1, utilizando 260 mililitros de esta el aderezo tendrá un 6% de vinagre, mientras que si se utiliza únicamente la marca Nº2, el aderezo tendrá un 10% de vinagre.

Siguiendo con esta lógica, si se utilizaran ambas marcas en igual proporción, es decir, 130 mililitros de cada una, la mezcla tendría un 8% de vinagre. Por lo tanto, es necesario utilizar un 75% de la marca Nº1 (con un 6% de vinagre), y un 25% de la marca Nº2 (con un 10% de vinagre), para lograr el deseado 7% de vinagre.

Así, deberán utilizarse 195 mililitros de la marca Nº1 (260 x 0.75 = 195), y 65 mililitros de la marca Nº2 (260 x 0.25 = 65).
