    Need help with turning word problems into an equation please

    Here is my problem I'm completely lost on for the past few hours, and can;t get any help until after it is due on monday. If you could please solve this for me and give me all the steps so I can go over it and learn it properly, and hopefully be able to do the rest on my own. Thanks very much.
    I need to define the variables, write the equation, and solve. My main problem is figuring out how to make this problem into an equation.

    16. Kingdom, a toy chain, placed a seasonal order for two different stuffed animals. The polar bears cost $11.25 each and the penguins cost $8.75 each. The total cost of the order is $2,042.50 for 210 pieces. How many of each animal were ordered?

    Number of polar bears ordered: ___________

    Number of penguins ordered: ___________

    Equation:_________________________________________ ____________

    Re: Need help with turning word problems into an equation please

    so I have been researchin all day on this and trying it a million different ways. I belive I would want 2 seperate equations but not quite sure, here are the equations I have came up with
    11.25x + 8.75y= 2,042.50
    x+y=210
    are these the correct equations? if so how do i use these to solve for x and y?
    I appreciate any help given as I've spent hours on this and am basically getting no where

    Correct equations! You must need some sleep

    From [2]: y = 210 - x ; substitute in [1]:
    11.25x + 8.75(210 - x) = 2042.50
    11.25x + 1837.50 - 8.75x = 2042.50

    OK? Wrapper up
