Incorrect. Look at the chart, and calculate the amount of acid (liters) that each solution will give. The amount of acid in solution 1 added to the amount of acid in solution 2 is represented by the following:

$\displaystyle{0.1}{\left({x}\right)}+{0.3}{\left({30}-{x}\right)}={7.5}\usepackage{cmbright}\Huge\$

Can you figure out the value of x in this equation?
