Excel 'nested IF' formula?

Can anyone capture the following logic in a nested-IF statement so I can copy/paste straight into Excel?

£0.01 - £4.99 10% for the amount of the selling price up to £4.99
£5.00 - £9.99 10% of the initial £4.99 plus 8% of the remaining selling price balance
£10.00 - £49.99 10% of the initial £4.99 plus 8% of the initial £5.00 - £9.99 plus 6% of the remaining selling price balance
£50.00 - £499.99 10% of the initial £4.99 plus 8% of the initial £5.00 - £9.99 plus 6% of the initial £10.00 - £49.99 plus 4% of the remaining selling price balance
Over £500 10% of the initial £4.99 plus 8% of the initial £5.00 - £9.99 plus 6% of the initial £10.00 - £49.99 plus 4% of the initial £50.00 - £499.99 plus 2% of the remaining closing value balance

Red Rain in Kerala?

I've read about a red rain in Kerala occured in 2001 and occurred again in 2006. It seems that the red color is due to some not identified organic corps contained into the rain.
What is the cause of this red rain ? Is it an alien invasion or a new human experiment?

POWER problem on physics?

Cycling. For a touring bicyclist the drag coefficient is 1, the frontal area is 0.463 m^2, and the coefficient of rolling friction is 0.0045. The rider has a mass of 50 kg, and her bike has mass 12 kg.

a.) To maintain a speed of 12 m/s (about 27 mi/h) on a level road, what must the rider's power output to the rear wheel be?
b.) For racing, the same rider uses a different bike with a coefficient of rolling friction 0.0030 and mass 9 kg. She also crouches down, reducing her drag coefficient to 0.88 and reducing her frontal area to 0.366 m^2. What must her power output to the rear wheel be then to maintain a speed of 12 m/s.
c.) For the situation in part (b), what power output is required to maintain a speed of 6 m/s? Note the great drop in power requirement when the speed is only halved.
