Hailie Massey · Answer 1

Let a be the amt of perfume A, and b be the amt of perfume B. We have been given that

a+b=3 and that a∗15+b∗35=63

From equation 1, we substitute b=3-a so as to get, a∗15 + (3-a) ∗35=63

which means, 15a+105-35a=63 which means, - 20a=-42

so a = 2.1 ounce and b = 0.9 ounce
