Need a formula for this math problem. Help!?

Relinda owns a tea shop and is creating a new mix of tea for her customers. She is using a standard black tea that sells for $7 per pound and a special orange flavor that sells for $11 per pound. She is planning to make a 40 pound batch of the mix and would like to sel it for $8.50 per pound. How much of each tea should she mix if she is not planning on making or losing any money with this mix?

I'm thinking it might be 7x+11(40-x) divided by 40 equals $8.50

My brain is melting!

The suggested formula is perfect!

Only thing to add:

x=number of pounds of black tea.
