Answer:

  1. Beachy Keen
  2. Shore Thing
  3. Shore Thing
  4. Beachy Keen
  5. Shore Thing

Step-by-step explanation:

The equation of the graph can be written by observing that ...

  the y-intercept is 200

  the graph has a rise of 200 for a run of 1, so the slope is 200

Then the price at Shore Thing is ...

  y = 200x + 200

__

The price at Beachy Keen is given as ...

  y = 249x + 100

__

The equation of the table can be written by observing that ...

  the y-intercept is 115

  the additional cost for 1 night is 230

Then the price at Seas the Day is ...

  y = 230x + 115

__

1) The nightly rate is the coefficient of x. Beachy Keen charges the highest nightly rate.

2) The y-intercept is the deposit. Shore Thing charges the highest deposit.

3) Shore Thing charges the lowest nightly rate.

4) Beachy Keen charges the lowest deposit.

5) The costs of a 6-night stay are ...

  • Shore Thing: 200(6) +200 = 1400
  • Beachy Keen: 249(6) +100 = 1594
  • Seas the Day: 230(6) +115 = 1495

Shore Thing charges least for a 6-night stay.
