Yes, a good chance that will work.
What value was the resistors they sold you? Or the color code?
Do you have a meter, VOM, DMM, multimeter, whichever your term may be?
You can use it to measure the resistor value and the voltage across it, your source voltage, and the curent thru it. You can also check your source voltage with it, so you won't be guessing.
You will find the meter to be invaluable if you are going to do much more of this kind of thing. It's well worth the investment! I'm not too sure I would go back to that same store for it, though.
