Question 774704
Two-part mixture.


L = 1.80 dollar/pound
H = 2.60 dollar/pound
T = 2.04 dollar/pound
u = How much pounds of the L candy, unknown
V = 3 pounds, the H candy


Only one unknown, so only need one equation:
{{{highlight((Lu+HV)/(u+V)=T)}}}
Solve for u and substitute the given, known values.
