Paul lands a home mortgage of $58,200 at a
qwelly [4]

Answer:

$72,100

Step-by-step explanation:

To calculate the total principal+interest payment, you can use the formula to find the future value:

FV=PV(1+i)^n

FV= Future value

PV= Present value= $58,200

i= Interest rate= 7.40%

n= Number of periods of time= 3 years

Now, you can replace the values on the formula:

FV=58,200*(1+0.0740)^3

FV=58,200*(1.0740)^3

FV=72,100

According to this, the answer is that the  total principal + interest  payment will be $72,100.

What is the rate of change for both of these tables. 25 pts
Rudiy27

Answer:

For the table on the left the rate of change is  22.8

For the table on the left the rate of change is -2

Step-by-step explanation:

The range of change is the slope. The slope can be found with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

<u>For the table on the left</u>

Choose two points. In this case you can choose (-1,-24), (4,90)

You can say that:

y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4

Substituting these values into the formula, you get:

m=\frac{-24-90}{-1-4}\\\\m=22.8

<u>For the table on the right</u>

Choose two points. You can choose (3,-6), (-6,12)

You can identify that:

y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6

Substituting these values into the formula, you get:

m=\frac{-6-12}{3-(-6)}\\\\m=-2
