Answer:  option b

 

Explanation: In simple words, collinearity refers to the condition under which some of the Independent variables in the model are related to each other. This  international between independents variables can result into incorrect results while fitting the model.

Therefore, collinearity causes problem as the analyst prepares a model on the basis that there will be two inputs one is dependent another is independent but due to this phenomenon the  expected input structure collides.

Hence from the above we can conclude that the economist should be concerned with col linearity.

Olivia bought a $1,874 sprinkler system with her credit card. Her credit card has an APR of 10.31%, compounded monthly. She made
Radda [10]

Answer:

Percentage of the total lifetime cost of the system that the original price made up = 59.07%

Explanation:

The monthly payments for the sprinkler system can be calculated using the formula for calculating the present value of an ordinary annuity as follows:

PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)

Where;

PV = Present value or original price of the sprinkler = $1,874

P = Monthly payment = ?

r = Monthly interest rate = APR / 12 = 10.31% / 12 = 0.1031 / 12 = 0.00859166666666667

n = number of months = number of years of payment * 12 = 4 * 12 = 48

Substitute the values into equation (1) and solve P, we have:

$1,874 = P * ((1 - (1 / (1 + 0.00859166666666667))^48) / 0.00859166666666667)

$1,874 = P * 39.1976732321759

P = $1,874 / 39.1976732321759

P = $47.81

Therefore, we have:

Total payment for the sprinkler = Monthly payments * Number of months = P * n = $47.81 * 48 = $2,294.88

Total cost in water = Cost in water per week * Number of weeks in a year * Number of years that Olivia kept the sprinkler system = $2.11 * 52 * 8 = $877.76

Total lifetime cost of the system = Total payment for the sprinkler + Total cost in water = $2,294.88 + $877.76 = $3,172.64

Percentage of the total lifetime cost of the system that the original price made up = (Original price of the sprinkler / Total lifetime cost of the system) * 100 = ($1,874 / $3,172.64) * 100 = 59.07%
