How many gallons of 80 percent solution must be mixed with 100 gallons of a 15 percent antifreeze solution to get a mixture that is 70 percent antifreeze?

For these types of problems, I recommend finding the initial amount of antifreeze. To find this value, multiply the percentage of antifreeze (15%) by the amount of solution (100 gallons). This gets:

0.15*100=15 gallons of antifreeze*

Now we need make an equation that represents this problem. We let x be the number of gallons of 80% solution.

(.80x+15)/(x+100)=0.70

The top of the equation represents the amount of antifreeze, while the bottom is the total volume of the solution. If we divide these values, we should get the final concentration %, .70.

Now we just need to manipulate the equation algebraically:

.80x+15=.70x+70

.10x=55

x=550 gallons of 80% solution

*If the concentration of a solution is given in percentage, it is probably referring to mass, not volume. Because of this, the values for the volume of antifreeze are actually untrue. But because the density of both substances remains the same, the final answer should be correct.
