The floor took me longer and more pennies (2ps) than I thought.
I had started with two £20 bags of 2ps, and that did what looked like almost 2/3 of the floor, so I went to the bank, and brought another £20 bag!
OMG that still wasn't enough, so I raided ours and a friends piggy banks, more coins, about £12 more... still not enough...
So I asked fellow Kent cachers to bring some to a Kent meet, and happily they provided some more 2ps. (thanks to you all, you know who you are!) But it still wasn't enough!
So my final thought was here, (the posted coords) where there were plenty of 2ps to be having... I got the final coins needed and the final price for the floor was £76.54! Yeah I know! that is a lot of 2ps! The floor looks brilliant, and it took 6 coats of varnish. I love it!
So to the puzzle... Consider
A = ?
B = ?
C = ?
The cache can be found at
N51 ( ( (A+B+C) x6) + (Ax19) ) -2
E000 ( ( (A+B+C) x14) - (Ax4) -B) -2
In case you might want my 2 pence worth…
