Question 1182238
<br>
Here is another non-algebraic method that allows for a non-algebraic solution.  It is an especially fast method if you are good with mental arithmetic.<br>
In the problem, 0% antifreeze is mixed with 60% antifreeze to get a mixture that is 8% antifreeze.<br>
Observe (perhaps using a number line) that 8% is 2/15 of the way from 0% to 60%.<br>
That means the 1.6 liters of 60% antifreeze being added is 2/15 of the mixture.<br>
That means the capacity of the radiator in liters is<br>
{{{(15/2)(1.6)=15(0.8)=12}}}<br>
