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:
23 years.
Step-by-step explanation:
It is given that the initial price of painting is $150 and its values increasing by 3% annually.
We need to find how many years will it take until it is doubled in value.
The value of painting after t years is given by
The value of painting after double is 300. Substitute y=300.
Divide both sides by 150.
Taking log both sides.
Therefore, the required number of years is 23.
