Step-by-step explanation:
Let's assume x = apple juice, y = orange juice, and z = cranberry juice
<u>x : y : z = 3/4 : 1/10 : 3/20</u>
If we were to make them all in the same denominator, x : y : z = 15/20 : 2/20 : 3/20.

1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
Based on the given values of briefcases presented, there is only a little chance that you would get the briefcase with the $500,000 considering that there are three. Therefore, the mathematically correct decision for this and why would be option A. <span>Take the $160,000, because it is greater than the expected value of the briefcases. Hope this answer helps.</span>
