Question 1125628: A scientist is working with two different concentrations of HCI. One bottle is 80% HCI and the other is 50% HCI. For their experiment they need 1 liter of 70% HCI. how many liters of the 80% solution do they need? How many liters of the 50% solution?

Not the best example. Concentrations of HCl above 40% not so practical; they don't keep well and will have some of the concentration lost quickly.

If you want the arithmetic anyway, then

x volume of 80%
1-x volume of 50%

liters of the 80% material
liters of the 50% material
