If you were getting 20% off of a £7.50 admission the new price would be £5.
This is due to the fact that 10% is 0.75

7.50 minus the 20% off, 1.50, would be £5.
Cf=cold faucet rate
hf=hot faucet rate
cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72
It takes 14.4 minutes.
