Answer:
(n^2 + n)/2 ways
Explanation:
Each time you can climb 1 or 2 steps to the top (n steps)
Number of ways climbing 1 step to the top = n combination 1 = n!/(n-1)1! = n(n-1)!/(n-1)! = n
Number of ways climbing 2 steps to the top = n combination 2 = n!/(n-2)!2! = n(n-1)(n-2)!/2(n-2)! = (n^2 - n)/2
Total number of ways = n + (n^2 - n)/2 = (2n + n^2 - n)/2 = (n^2 + n)/2 ways
Answer:
B. Check the person's credit history to make sure he or she pays debts on time.
Explanation:
Applying for a loan from a bank is when a person wants to borrow money from the bank for his personal requirements. This is also one of the ways a bank does business, incurring interest while also 'helping out' a person in need.
One factor that banks take into consideration for approving a loan to a person is checking the credit history of that person. This means that the bank will investigate the person's credit score and how often he pays his credit bills. Depending on the pattern of the payment, a bank will be able to understand the dependability of the person for a loan's payment.
Thus, the correct answer is option B.
In class 2 ., The Model D is the Top/ favorite one having highest market return (24%) with lowest inventory cost ($79)
Explanation:
To Determine the value of the inventory at the lower of cost or market applied to each item in the inventory. simply we should calculate the profit margin for each category
Profit margin = (market value - cost price) = Profit ÷ cost price × 100
Class 1:
Model A
46 $116 $139
Profit margin = (139 - 116) = 23 ÷ 116 × 100 = 19.32%
Model B
49 243 239
Profit margin = (239 - 243)= -4 ÷ 243 × 100 = - 1.65% (loss)
Model C
43 233 252
Profit margin = (252 - 233) = 19 ÷ 233 × 100 = 8.15%
Class 2:
Model D
37 79 98
Profit margin = (98 - 79) = 19 ÷ 79 × 100 = 24%
Model E
6 151 130
Profit margin = (130 - 151) = - 21 ÷ 79 × 100 = -13.91 % (loss)
Result
In class 1
Model A is preferable., It has the lowest inventory value and has highest market value (Returns) at 19.82%
In class 2
Model D is preferable., It has the lowest inventory value and has highest market value (Returns) at 24%
Overall the Model D is the Top/ favorite one having highest market return with lowest inventory cost
