Maki uses 20 gallons of a solution with an unknown ethanol concentration and 60 gallons of a 12% ethanol solution to make 80 gallons of a 10% solution. The table shows the amount of each solution. A table titled Ethanol Mixture, showing Gallons, Ethanol Concentration, and Total. The first row shows x percent Ethanol, 20, x, and blank. The second row shows, 12 percent Ethanol, 60, 0.12, and 7.2 The third row shows Mixture, with 80, 0.10, and blank. What is the value of x, the concentration of the unknown ethanol solution? 0.02 0.04 0.05 0.08

4%

Step-by-step explanation:

We can write the following equation:

20 * (x / 100) + 60 * 0.12 = 80 * 0.10 (Note that since we're writing the percentages as decimals, x% becomes x / 100 as a decimal.)

x / 5 + 7.2 = 8

x / 5 = 0.8

x = 4%
