Trying to calculate a weighted average? ?

If I have a 57% and

a 67

% and it is worth 20% of my grade. Then I have a 92 worth 50% of my grade? How do I calculate that? Thanks!

    (57% x 20%) + (67% x 20%) + (92% x 50%) = 70.8%, or..............

    (57% + 67%) x 20% + (92% x 50%) = 70.8%

    'and it is worth 20% of my grade' 

    Not clear if each is worth 20% or each is worth 10% for a total of 20%.  I will assume both are worth 20%.

    weighted average = ( 57% * 0.2 + 67% * 0.2 + 92% * 0.5) / (0.2 + 0.2 + 0.5) = 78.7%
