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

Question

campbell_st · Answer

let carlos = x

benita = 2x 

alice = x -15

so 

x + 2x + x -15 = 150

solve for x, which is the weight carlos collected... then you can find the rest.

ray_sihota · Answer

X+2X+X-15=150
4X-15=150
4X=165
X=41.25
B=8.250
A=26.25

campbell_st · Answer

well the equation I wrote was 

4x - 15 = 150

solve for x

ray_sihota · Answer

then add 15 to both sides 4x=165
x=41.25

campbell_st · Answer

yep... so carlos collected 41.25 lb... 

based on what's in the question, that's correct
