Solution:
Given that
G being the midpoint of FH implies

Additionally, we have

Hence, we can express

Therefore, 
It is the one that has been picked, the one positioned on top.
The answer is: Option 'B' is the right choice.
Detailed breakdown:
Her annual income totals $14,700
Her monthly earnings would then be

She desires to buy new items after covering her expenses and saving for her college education.
Based on the provided options:
Only Budgets B and D appear to reflect the correct monthly income, which is $1,225.
In Budget B,
The total savings amount to $400
In Budget D,
The total savings also amount to $400
Thus, Budget B is optimal for achieving her objectives.
As a result, Option 'B' is the correct choice.
Part A
To identify the values of x that make 2x−1 positive
⇒ 2x - 1 > 0
⇒ 2x > 1
⇒ x > 
As a result, for any x greater than

, the expression 2x-1 is positive
Part B
To find values of y making 21−37 negative
⇒ 21-3y < 0
⇒ 21 < 3y
⇒ 7 < y
Thus, for all y values exceeding 7, the expression 21-3y is negative
Part C
To identify values of c that digit 5−3c greater than 80
⇒ 5-3c > 80
⇒ -3c > 75
⇒ -c > 25
⇒ c < -25
Therefore, for values of c less than -25, the expression 5-3c surpasses 80
Assuming that every material in their respective categories has an equal likelihood of selection.
Categories:
(a) Wood types for cabinets: birch, maple, cherry.
Each wood type has a selection probability of 1/3.
(b) Finish types: transparent, semi-transparent.
Each finish type has a 1/2 chance of being selected.
(c) Knob types: bronze, steel, wood.
Each knob material carries a probability of 1/3.
The selection of materials for the cabinet, finish, and knobs is independent of one another.
Consequently,
Probability(birch wood AND bronze knob) = (1/3)*(1/3) = 1/9
Probability(wood knob) = 1/3
Probability(transparent stain) = 1/2
Probability(cherry wood AND semi-transparent stain) = (1/3)*(1/2) = 1/6
