Answer:
In 1980
Explanation:
Year Salary Percentage Salary Increase CPI Increase
1970 $12,000 - -
1980 $24,000 100 50
1990 $36,000 50 83.3
As can be seen in the table, the Professor's salary increase from 1970 to 1980 was twice as much as the CPI increase during the same period.
On the contrary, his salary increase from 1980 to 1990 was significantly less than the CPI increase during the same period.
Therefore, the professor's salary was highest in 1980.
Answer:
a) 32 refrigerators
b) 28.39 approximately 29 refrigerators
Explanation:
Given:
Cost of order, S = $100
H = 20% of 500 = 100
Cost of refrigerator = $500
Annual demand, D = 500
S.d = 10
Lead time, L = 7 days.
a) To find the economic order quantity, Q_opt, let's use the formula:
The economic order quantity is 32 refrigerators.
b) The reorder point, R, is calculated as:
R = (d' * L) + ( z * s.d)
Where d' is daily demand which is calculated by dividing annual demand by 365 days.
d' = 500/365 = 1.37
At 97% service probability.
Using the excel function, NORMSINV(0.97) = 1.88.
Therefore z = 1.88
Solving for R, we have:
R = (1.37 * 7) + (1.88 * 10)
= 28.39
≈ 29
If the distributor wants a 97% service probability, the reorder point, R, should be 29 refrigerators
Answer:
d.) discretionary expenses
Explanation:
We can explain going further into what is each item.
<u>A and B are your income </u>(for this question don’t sweat about the difference between gross and realized). They will constitute all the money you have in that period (the period will depend on the regularity of your income, it could be weekly, monthly, etc.).
Your fixed expenses are the things you will expend money on which, no matter what happens, will not change (it could be your rent, tax, health insurance, etc.).
Discretionary expenses, however, are costs that are things that you WANT, not NEED. It could go anywhere from a new shoe to a new boat (if you´re feeling rich, that is lol). That kind of expense will impact your available money (hey, nothing is free) but is not part of your budget as it is not a planned cost.
However, is important to note that if you wanna be super Monica Geller with your money you should forecast your discretionary expenses. Using your history as a base for calculating will eliminate most of the margin error.
Answer:
<h2>
Value of X = 1</h2>
<h2>
Value of y = 3</h2>
Solution,
Using substitution method,
y + x = 4
Move 'x' to the left hand side and change its sign:
y = 4 - x --------> equation (i)
Now,
2y - X = 5
putting the value of y from equation (i)
2( 4 - x ) - X = 5
8 - 2x - x = 5
8 - 3x = 5
- 3x = 5 - 8
- 3x = - 3
The difference sign (-) will be cancelled in both sides
3x = 3
3x/3 = 3/3
X = 1
Value of X is 1
Now, replacing the value of X in equation (i)
y = 4 - x
= 4 - 1
= 3
Value of y is 3
Hope this helps...
Good luck on your assignment...
