The total sales made by a salesperson was $25,000 after 3 months and $68,000 after 23 months. Predict the total sales after 39 months. A) $102,400 B) $102,370 C) $102,500 D) $102,442

   A)  $102,400

Step-by-step explanation:

For these answers, we must assume the increase is linear.

The two-point form of the equation for a line is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

Filling in the given (x, y) values of (3, 25000) and (23, 68000), we have ...

  y = (68000 -25000)/(23 -3)(x -3) +25000

  y = 2150x +18,550

Then for x = 39, we find the predicted sales to be ...

  y = (2150)(39) +18,550 = 102,400

The predicted sales after 39 months is $102,400.

_____

The graph shows sales in thousands of dollars.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
