Question 645893: The radiator in a car is filled with a solution of 60% antifreeze amd 40% water. The manufacturer of the antifreeze suggests that. for summer driving, optimal cooling of the engine is obtained with only 40% antifreeze. If the capacity of the radiator is 3.6 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level?

The radiator in a car is filled with a solution of 60% antifreeze amd 40% water. The manufacturer of the antifreeze suggests that. for summer driving, optimal cooling of the engine is obtained with only 40% antifreeze. If the capacity of the radiator is 3.6 L, how much coolant should be drained and replaced with water to reduce the antifreeze concentration to the recommended level?
let x=amt of 60% coolant should be drained and replaced with water
3.6-x=amt of 60% coolant remaining
..
60%(3.6-x)+0%x=40%*3.6
2.16-.6x=1.44
.6x=2.16-1.44=.72
x=1.2
amt of 60% coolant should be drained and replaced with water=1.2 L
