Temperature transmitter question

Hi There,

I have a question regarding temperature transmitter. Can someone please help me to solve this problme? I really prompt reply in this matter.

A -10V to +10V temperature transmitter is calibrated to measure from-50’C to +300’C.At a temperature of +76’C, what would be the expected voltage output from the transmitter?

(76/(300-(-50))x(10-(-10))=4.343Vdc
