Kristen wants to make 7.5 ounces of a 25% jasmine essential oil. She only has a 15% jasmine mixture and a 30% jasmine mixture available. How much of each mixture should she combine to create the desired oil?

let the amount of the 15% mixture be x ounces
then the amount of the 30% mix is 7.5x
.15x + .30(7.5x) = .25(7.5)
times 100
15x + 30(7.5x) = 25(7.5)
15x + 225  30x = 187.5
15x = 37.5
x = 2.5
Use 2.5 ounces of the 15% mix and
5 ounces of the 30% mix
