Is that all? My Algebra is freackin hard compared to this. Anyways, The way I understand this, is that we will have 3 (liters of water) +0.5 (half a liter of lemonade) =3.5 liters of liquid

so the question would be: how many times does  fit into 3.5?

if you want to divide by a fraction, you need to multiply by the reverse of it. 

so the answer is: 10 servings of lemonade ( and a little bit will be left over for half a serving).
Hope this helps!

The salary pay is more than the hourly pay based on the typical hours worked each week given in the table. Therefore, the employee would probably want to choose the salaried pay.
