George wants to buy a bike that costs 200 dollars. He decides to do odd jobs to earn the money for the bike. In June, George mowed 10 lawns, washed 8 cars, and waxed 6 cars. How much more money does he need to buy the bike?
You need to say a little bit more detail so we can solve it because there is no way to solve it without knowing at least how much money he got from one of the jobs.
