If 0.25 oz of yeast is used, then 50oz of flour is needed.
It would require 0.5 oz of yeast for 90 oz the flour.
We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:
So if we use 0.25 oz of yeast:
if 0.25 oz of yeast is used, then 50oz of flour is needed.
If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:
So, if we use f = 90 0z of flour:
It would require 0.5 oz of yeast.
Let us consider the expression:
Now, the quotient of power rules says that the numbers that have same base can be find by subtracting if powers are with same sign
And adding if powers are with opposite sign.
We will solve equation (1) by this quotient of power rule.
So, it can be rewritten as:
Answer: 5A 6C 7D
