Honestly I think that is your call to make.
An "average" a book usually pays out about half of what you put in. So if you spend $300 on a book ( I have no idea how many tickets are in a $1, or $3, and so on book for your state), you can expect to get back about $150 dollars.
Of course some times people do much better and some times people do much worse. You could find a ticket worth $1,000 in there or a jackpot ticket or you may only have ten or twenty winners of less then $10 each. It's a gamble either way.
The way I usually look at it is, are you ok with losing half of your investment? In other words do you actually have the expendable money to be gambling with. If the answer is yes then go ahead. But be sure it's something you can afford to do.
Also know that hitting like you do is considered lucky, not something that should happen all the time. Don't be disappointed if you don't find any decent winners in that entire book. Being in flordia though, your tickets seem to be decent in paying out compared to here in PA.
