    Post price question

    Cindy wants to paint her office. She can buy three cans of the same-priced paint
    and three identical brushes for $21, or she can buy four cans of the same paint
    and one brush for $22. How much does a can of paint cost?

    Set up a system of equations. Let x = the price of a can of paint and y = the price of a brush.

    3x + 3y = 21
    4x + y = 22

    Does this make sense?
