Describe the effect an increase in i, the interest rate applied to the present value, has on the monthly payment P in the formul

VARVARA [1.3K]

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,

$P=\frac{i \times PV}{1-(1+i)^{-n} }$ ,

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 $(1+i)^{n}$ increases.

This gives us that, $\frac{1}{(1+i)^{n} }$ decreases and so $1-\frac{1}{(1+i)^{n}}$ decreases

Therefore, $\frac{1}{1-(1+i)^{-n} }$ increases.

So, we get that as i increases , the value of P will increase.

Hence, option B is correct.

Darren can get to work in 30 minutes. the speed limit is 35 mph, but there are three stop lights. with the traffic and lights, h

Radda [10]

To solve this problem you must apply the proccedure shown below:
1. You have that Darren can get to work in $30 minutes$ and with the traffic and lights, he can average $30 mph$ .Therefore, you must apply the formula for calculate the distance, which is:
 $d=Vt
$ 
Where $V$ is the speed and $t
$ is the time.
2. The time in hours is:
 $30 min=1/2 h
$ 
3. Substituying values, you have:
 $d=(30 mph)(1/2 h) \\ d=15 miles$
 The answer is: $15 miles$
