    1. Simplify: (-4)(5)(-7)(2)

    2. Two trains are approaching each other on the same track. They are 500 miles from each other. One train is traveling at 40 mph, the other at 60 mph. A bird is flying back and forth between them at 150 mph. How long before they collide?

    3. Solve for y: x = (y-b) / m

    4. Graph x - y = 4

    5. A person wants to buy an article, and has a spending limit of $700.
    If there is a 10% sales tax, write an inequality that shows the price range in in which he should be looking.
