Question 307395: How many bags with 0.08 cement should mix with 2 bags of 0.63 cement to produce a mix containing 0.19 cement?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x = amount of .08 cement.
2= amount of .63 cement
x+2 = amount of .19 cement
The equation to solve is
.08x + .63*2= .19(x+2)
.08x + 1.26 =.19x+.38
Subtract .08x from each side:
.08x-.08x + 1.26= .19x-.08x + .38
1.26=.11x + .38
Subtract .38 from each side:
1.26-.38 = .11x+.38-.38
.88=.11x
x=.88/.11= 8 bags
