Hi, Best to proceed in a traditional manner by forming the blend algebraically
I. Assigning the variable
Let x represent the amount of the green tea mixture used in the final blend
II.Writing as we Read***Mixing to form $2.00 blend
$1.25*x + 3.00*60oz = $2.00 (60oz + x)
III.solving for x
60oz = .75x
60oz/.75 = x
x = 80oz, the amount of the green tea mixture used
IV. CHECKING Our Answer***
$1.25*80 + $3.00*60 = $100 + $180 = $280 = $2.00*140
