HELP PLZ!! I NEED HELP!

Step-by-step explanation:

The amount Lila and Wassim plan to save is ...

  (£13 +13)(9) = £234

__

The charges they expect to incur are a per-person charge and a tent pitch charge. Since they expect to stay 10 nights, the special rate means they will only be charged for 8 nights.

per-person charge

  per-person-per-night charge = (2 persons)(8 nights)(£6 per person-night)

  = £96

tent pitch charge

To determine the tent pitch area required, we need to find the area of the tent:

  A = LW = (4.2 m)(2.3 m) = 9.66 m²

This is less than 10 square meters, so we can expect the pitch charge to be £15 per night for 8 nights.

  tent pitch charge = (£15/night)(8 nights) = £120

So, the total of camp site charges is expected to be ...

  person charge + pitch charge = £96 +120 = £216

__

The expected savings exceeds the expected charges by ...

  £234 -216 = £18

Lila and Wassim will have enough saved, with £18 extra.

i belive those are the ones that are under 90 degreese.
