Solution :
At every stage the formula used will be :

After the junior year, Aunt Mabel's bank balance will be :

= $ 7,322.65
Aunt Mabel's bank balance after sophomore year will be :
7,322.65 + 1000 = $ 8,322.65

= $ 8060.677
After the freshman year, bank balance of Aunt Mable's will be :
8060.677 + 6000 = $ 14,060.677

= $ 14.0606
If Aunt Mabel can predict the interest rate with accuracy, she will have to deposit :
$ 14.0606 + $ 9000 = $ 9,014.06

= $ 8,565.241
Answer:
A. Selection of the appropriate causal variable Y is important
Explanation:
We have this function, Y = f(X).
From this function we can see that Y is dependent on X. That is, it is a function of X. Y is not a causal variable. A causal variable is a variable that is able to influence the variable of interest. From this question Y is the variable of interest. It is the dependent variable. The independent variable is X and it is the causal variable.
Therefore the incorrect one is Selection of the appropriate causal variable Y is important
Answer:
Plan A cost $26,000
Explanation:
(21 * 6) + (13 * 18) + (19 * 2) + (7*4) + (11 * 2) + (4 * 18)
