Question 194686: LS Antifreese contains 74% ethylene glycol. BT oil Antifreeze contains 58% ethylene glycol. How many gallons of each antifreeze must be used to make 10 gallons of antifreeze that is 68% ethylene glycol? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! .74x+.58(10-x)=.68*10
.74x+5.8-.58x=6.8
.16x=6.8-5.8
.16x=1
x=1/.16
x=6.25 gal. of 74% is used.
10-6.25=3.75 gal. of 58% is used.
Proof:
.74*6.25+.58*3.75=.68*10
4.625+2.175=6.8
6.8=6.8
