## Homework Statement

How much milk at 11 degrees Celcius was added to 0.16 kg of coffee at 91 degrees Celcius if the final temperature is 76.8 degrees Celcius?

## Homework Equations

Well my teacher explained how to rearrange cm∆T = cm∆T to somehow come up with an equation to solve for the final temperature: Tf = T

_{1}* m

_{1}+ T

_{2}* m

_{2}/ (m

_{1}+ m

_{2}) How would I rearrange that to solve for one of the masses?

## The Attempt at a Solution

No idea :(
