Real-Life Math -- Solution

Charts really are the best way to visualize this information by allowing you to compare reservations to total available campsites.

Motorhomes/RVsFri.Sat.Sun.




Reserved (1 day)20015
Reserved (2 days)75750
Reserved (3 days)505050




Total Reserved14512565
Minus Total Available-150-150-150




Open Spaces Available52585

So how many do you have open?

Friday
Open = 150 available - (50 + 20 + 75)
Open = 150 - 145
Open = 5

Saturday
Open = 150 - (50 + 75)
Open = 150 - 125
Open = 25

Sunday
Open = 150 - (50 + 15)
Open = 150 - 65
Open = 85

You can add this information to the bottom of your chart. We did that with the chart for the tents:

TentsFri.Sat.Sun.




Reserved (1 day)150050

Reserved (3 days)250250250




Total Reserved700550300
Minus Total Available-700-700-700




Open Spaces Available0150400

Here are the calculations:

Friday
Open = 700 - (250 + 150 + 300)
Open = 700 - 700
Open = 0

Saturday
Open = 700 - (250 + 300)
Open = 700 - 550
Open = 150

Sunday
Open = 700 - (250 + 50)
Open = 700 - 300
Open = 400

Most park warderns use charts to track campsites, work schedules and park openings and closings.
