Answer:
diminishing marginal rates of substitution.
Explanation:
Based on the information provided within the question it can be said that the principle that captures this is known as diminishing marginal rates of substitution. Like mentioned in the question this refers to the fact that a consumer chooses to replace a product instead of actually buying more.

Answer: (D) 5.90%
Explanation: David is going to buy a new car at $21,349.
The down payment is $3,000.
Loan amount (Present value) = $21,349 - $3,000
Loan amount (Present Value) = $18,349
Installment amount (pmt) = $352
As the payment is made monthly (12 months in a year),
Number of payments = 5 * 12
Number of payments = 60
Using the rate option in excel,
Insert the variables into the option, we get
By inserting the above formula in excel we get,
Rate = 0.47%
Rate of 0.47% is monthly, to get APR
APR = 0.0586
APR = 5.86% or 5.90%
Therefore the correct option is 5.90%.
