Lindsey holt owns stock in the galloway gems company. she knows she will receive a $1.50 dividend each quarter. given this, you know for sure that she purchased which type of stock

I would say that this would be a guaranteed dividend stock on preferred shares because it must be paid on a regular basis as an obligation, and it would take precedence over other payments. Such a dividend is cumulative which means that if a payment is missed, no common stock payments can be made until that dividend is paid.
