Answer:
<em>Equation:
</em>
<em>HCL + HCL = HCL
</em>
<em><u>0.30x + 0.45(50-x) = 0.35*50
</u></em>
<em><u>Multiply thru by 100 to get:
</u></em>
<em><u>30x + 45*50 - 45x = 35*50</u></em>
<em><u>-15x = -10*50
</u></em>
<em><u>x = (2/3)50
</u></em>
<em><u>x = 33 1/3 liters (amt. of 30% solution needed in the mixture)
</u></em>
<em><u>50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture)
</u></em>

Answer:
4 runs
Step-by-step explanation:
Set up the average equation as follows:
Remember 12 will be on the bottom since you have to add an extra score; they have 11 games already. Now, just solve for x.
6 x 12 = 68 + x
72 = 68 + x
4 = x
