Jamie mowed 7 lawns. He earned $10, $15, $12, $15, $8, and $15 for six lawns. How much did he earn the seventh time if the mean of the data is $12?

And can you please provide the work? I've tried adding all and dividing by total which I got 75. I just don't know what to do on how to find the number that would give me 12 as the question asks.
