Help with numbers
I have an issue which I would appreciate help.
I have a spreadhseet of which a simplified extract is included.
I have used formula in column D =IF(B2>20,(0.45×B2),"£10")
What I am trying to achieve, but just keep getting lost is Column D is per formula, however I would like it to be able to take into account column C. If Column C =1h, then Column D should be =IF(B2>20,(0.45×B2),"£10") but add an extra £10 to the final value. If Column C is blank than formula in D to work as it is at moment. And if Column C is >1h, then the final result in D to increase in increment of 10, so 1h=10, 2h=20, 3h=30 etc etc.
I thought I could do it with and IF&AND Formula but I keep getting syntax errors, or just getting no result.
This is a simplified version of a larger more complex table but using this as proof of concept.
Any help would be appreciated.
