Find Max within range and add $15

[hopegriffin]

Hello Gurus!

I am working with a small table that shows prices and the total. I am trying to write a macro to find the highest price in the column N range. I was able to do this but of course it finds the grand total. I've uploaded a sample sheet. I have two rows that have prices in column N. I need to find the highest one and add $15. Then I'd like the one that has the added $15 to be highlighted or bolded so I can tell which one has the fee included.

I really appreciate any assistance. Thank you!!
