Below is a question a came across
Question: One dose of secret formula is made from 1/6 ounce of Substance X and 2/3 ounce of Substance Z. How many doses are in a 10-ounce vial of secret formula?
--------------------------------------------------------
This is my solution below.
if 1 dose = (1/6X + 2/3Z) ounce, then
x dose = 10 ounce.
I cross multiplied and made x dose the subject of the formula.
x dose = (1 dose * 10 ounce ) / (1/6X + 2/3Z)
I didn't simplify further because of the X and Z in the equation.
Textbook solution is below
1 dose = 1/6 + 2/3 = 5/6 ounces, so therefore
number of doses (x) in 10 0unces = (1 dose * 10 ounces) / (5/6 ounces) = 12 ounces.
My question is since why did they ignore the x and Z in the equation. Kindly help me understand why I should ignore the X and Z
