Answer:
Step-by-step explanation:
We first begin by finding how much the total expenses will be;
£6 per person per night = £6 * 2persons * 10nights = £120
They also need to pay for 8 nights out of 10 for the ground surface of the tent pitch. Since their tent is 9.66m², it's less than 10m² so they get to pay £15 * 8 = £120. We calculate for only one tent because they're sharing.
Their total expenses are £120 + £120 = £240.
Now let's look at their savings;
£13 * 2 persons * 9 weeks = £234
They will not have enough money for their holiday because they are £6 short of the £240 funds required.

The first moment (AKA the average is..)
The second moment is..
Answer:
