I’m trying to work out some hire prices using a formula, where the weekly cost of item is used to calculate the daily cost of it.

I have an item that cost me £1000, and I have decided that the weekly hire price is this figure divided by 10, so £100 a week. The daily price is calculated by dividing that by 3, so £33.33. However, I want the spreadsheet to round this up to £33.50. How do I use the ROUND function to do this?

At the moment I have:

Weekly cost = {Purchase Cost}/10

Then, daily cost = {Weekly Cost}/3

For both, I want it to round to the next 50p.

Thanks!
