Question

1. The amount of money Travis earns is given in the table.

Answer 1

Answer:

Step-by-step explanation:

(3,37.5),(5,62.5)

slope(m) = (y2 - y1) / (x2 - x1)

         m = (62.5 - 37.5) / (5 - 3)

         m = 25 / 2

         m = 12.5 <==== travis earns $ 12.50 per hr

so if he worked 20 hrs......thats 12.5 * 20 = $ 250 <== ur answer

Answer 2

Answer:

  $250

Step-by-step explanation:

The numbers in the table indicate a proportional relationship between earnings and hours worked. Among other things, that means you can find the earnings for 20 hours by using any table values that sum to 20 hours.

For example, 9 hours + 11 hours = 20 hours, so the earnings would be ...

  $112.50 +137.50 = $250.00 . . . for 20 hours

You could also use 4×5 hours = 20 hours, so ...

  4×$62.50 = $250 . . . for 20 hours

__

Or, you can figure ...

  $37.50/(3 h) = $12.50/h

so the pay for 20 hours is ...

  (20 h)×($12.50/h) = $250.00
