Suppose there are exactly 9 people on a bus in Seattle, and the average of their yearly incomes is $65,000. At the next stop, the highest paid person on the bus (with an income of $120,000 per year) gets off, and Bill Gates gets on. Mr. Gates makes 7.6 billion dollars a year. Q9a: What is the new average salary of people on the bus?

$844496111

Step-by-step explanation:

Size, n = 9

Initial average = 65000

Average = total sum / size

Initial Sum = 9 * 65000

Initial sum = $585,000

New average = ((585,000 - 120,000 + 7,600,000,000)) / 9

New average =

$7600465000 / 9

= $844496111. 11

= $844496111

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
