Answer: £210
Step-by-step explanation:
you do the cm they given you so if it’s 630cm x 120cm = 75,600
30cm x 30cm = 900cm
75,600 divided by 900 = 84
£2.50 x 84 = £210
Notice that
2010 ≡ 1 mod 2009
2011 ≡ 2 mod 2009
2012 ≡ 3 mod 2009
...
4017 ≡ 2008 mod 2009
4018 ≡ 0 mod 2009
So really, <em>S</em> is just the sum of the first 2008 positive integers:

where we invoke the formula

and so <em>S</em> ≡ 0 mod 2009.
