Solving an equation
According to the rules of a TV game show, every time a contestant answers a question correctly, th prize money for the question is awarded to the contestant, but for each question answered incorrectly, the prize money for the question is deducted from the contestant's total money. Contestant Joe answered a question worth $1,200 incorrectly and then answered a question worth $600 correctly. If Joe had $1,000 at the start of the show, how much money does he have after answering these two questions?
