George wants to buy a bike that cost 200 dollars he decides to do odd jobs to earn the money for the bike in june george mowed 10 lawns washed 8cars and waxed 6 cars how much money does he need to buy the bike?

Multiply how much he makes for 1 job by how many times he did it: lawns: 10x10=$100. Car washes: 5x8=$40. Car waxes: 8x6=$48. Add them all together: 100+40+48=188. Subtract what he made from much he needs: 200-188=$12. He needs $12 more :)
