Step-by-step explanation:
If you borrow $120,000 at an APR of 7% for 25 years, you will pay $848.13 per month. If you
borrow the same amount at the same APR for 30 years, you will pay $798.36 per month.
a. What is the total interest paid on the 25-year mortgage? <em>$134,439.</em>
5y+4x
5(10) + 4(-5)
50 - 20
30
Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
You have to give the problem and not just the options for me to solve
