\text{Alte Preis pro ml:} \ \frac{2\text{€}}{100ml} = 0.02\text{€/ml}

\text{Neue Preis pro ml:} \ \frac{2\text{€}}{75ml} \approx 0.0267\text{€/ml}

\text{Prozentuale Veränderung:} \ \frac{0.0267\text{€/ml} - 0.02\text{€/ml}}{0.02\text{€/ml}} \times 100\%

\text{Prozentuale Veränderung:} \ \frac{0.0067\text{€/ml}}{0.02\text{€/ml}} \times 100\% = 33.5 \%

\text{Antwort:} \ 33.5\%
