While building his catapult, Aiden tested several different designs. He varied the arm length of his catapult and recorded the horizontal distance between where the ball was launched and where it landed for each arm length. The table presents Aiden's data showing the length of the catapult arm in relation to the horizontal distance the catapult launched the tennis ball.

Length of catapult arm (cm) Horizontal Distance (cm)
60 320
80 352.4
100 386.8
60 288.1
70 315
75 322
90 362
100 390
85 350
95 398
What is the equation of the line of best fit for Aiden's data?
Enter the correct answer in the box by replacing m and b in the equation. Round each number to the nearest tenth (this equation over here) y=mx+b

 $525,341.20

Explanation:

30 years = 30*12 = 360 months

If the monthly payment is $2,223.17 for 360 months, then you'll pay back a total of 2223.17*360 = 800,341.20 dollars overall.

Subtract off the amount financed, or amount loaned, to get the total interest.

800,341.20 - 275,000 = 525,341.20 is the amount of interest paid (in dollars).

This works because effectively, the total amount paid back consists of principal + interest. The principal is the amount the bank loans you.

So we could rephrase that last equation into saying

principal + interest = 275,000 + 525,341.20 = 800,341.20 = total amount paid back.
