Respuesta :
he's right because if you chose woodland to stay for 4 nights it would cost you 220$ and if you chose campgrounds it would cost you 140$.
Answer:
For 4 nights stay we can stay in any campgrounds, but for more than 4 nights we should prefer Forest park Campgrounds.
Step-by-step explanation:
Forest park Campgrounds charges a membership fees = $100
and charges per night = $35
Charges for 4 nights stay
Total charges for 4 nights = 100 + 35×4
                    = 100 + 140
                    = $240
Charges for 5 nights stay = 100 + 35×5
                     = 100 + 175
                     = $275
Woodland Campground charges a membership fees = $20
and charges per night = $55
Charges for 4 nights stay = $20 + $55×4
                     = 20 + 220
                     = $240
Charges for 5 nights stay = 20 + 55×5
                      = 20 + 275
                      = $295
Therefore, for 4 nights stay we can stay in any campgrounds because charges for both are same for 4 nights.
But for more than 4 nights we should stay in Forest park Campgrounds because Forest park charges less than other campgrounds.
