Answer:
B. An increase in i, the interest rate, will create an increase in P, the monthly payment.
Step-by-step explanation:
We have the formula for the monthly payment as,
,
where P = monthly payment, i = rate of interest, PV = present value and n = time period.
Now, as i increase we get that (1+i) increases and so increases.
This gives us that, decreases and so
decreases
Therefore, increases.
So, we get that as i increases , the value of P will increase.
Hence, option B is correct.
Answer:
and
Step-by-step explanation:
when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):
then you need to include these two possible solutions:
