The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.
Given to us,
For Trial 1,
A = 2 oz
B = 4 oz
C = 4 oz
Percentage of rose oil = 22%
weight of trail 1 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 1 = weight of trail 1 x Percentage of rose oil in 1
= 10 oz x 22% = 2.2 oz
total ounces of perfume in trial 1
= weight of trail - Weight of rose oil in trial 1
= 10 - 2.2 = 7.8 oz
For Trial 2,
A = 4 oz
B = 2 oz
C = 4 oz
Percentage of rose oil = 27%
Total weight of trail 2 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial2 = weight of trail 2 x Percentage of rose oil in 2
= 10 oz x 27% = 2.7 oz
total ounces of perfume in trial 2
= weight of trial 2 - Weight of rose oil in trial 2
= 10 - 2.7 = 7.3 oz
For Trial 3,
A = 1 oz
B = 7 oz
C = 2 oz
Percentage of rose oil = 23.50%
Total weight of trail 3 = A+ B+ C = 2+ 4+ 4 = 10 oz.
Weight of rose oil in trial 3= weight of trail 3 x Percentage of rose oil in 3
= 10 oz x 23.50% = 2.350 oz
total ounces of perfume in trial 3
= weight of trail - Weight of rose oil in trial 3
= 10 - 2.2 = 7.8 oz
Hence, The total ounces of perfume in trials 1, 2, and 3 are 7.8 oz, 7.3 oz, and 7.65 oz.
