Return Marginal Tax Rate

I'm attaching an example.

I need to choose a marginal tax rate based on the YTD earnings in column B and the table in columns E and F. The values in E are the highest amount allowed for that tax bracked. I'd like the appropriate marginal rate to be returned in column C. Is this possible? The only formulas I can think of are a big string of IF statements.

I know you guys have an easier way!
