Question 162415
    70 oz of potpourri that is 80% lavender are combined with a potpourri that is 60% lavender. The resulting potpourri is 74% lavender. How much of the potpourri that is 60% lavender is used?
.
Let x = amount of 60% lavender
.
.80(70) + .60x = .74(70+x)
.80(70) + .60x = .74(70+x)
56 + .60x = 51.8 + .74x
56 = 51.8 + .14x
56 = 51.8 + .14x
4.2 = .14x
30 oz = x (amount of 60% lavender)
