Together Alice, Benita and Carlos collected 150 pounds of Aluminum cans for recycling. Benita collect twice as many pound as carlos while Alice collected 15 POUNDS LESS THEN CARLOS. FIND THE NUMBER OF POUNDS EACH COLLECTED
A+B+C=150
A=C-15
B=2C
C-15+2C+C=150
4C=150+15
4C=165
(4C=165)/4
C=41.25
A=41.25-15=26.25
B=2*41.25=82.5
Carlos collected 41.25 lbs, Alice collected 26.25 lbs, and Benita collected 82.5 lbs.
