Sorry to say but you are hardly meet up with a x40 wager requirements and still remain in profit with a slot game, except on rare occasions where you are extremely lucky..

First off, 40x wager requirement is to high for a $5 deposit bonus, really high if I must be honest but I admit it might not be that much high for another user.
Secondly, limiting the wager count to only slot games is yet another unrighteous rule which further makes achieving the x40 wager and remaining in a profit a possible mirage, this is why is always very important to read rules, and make sure to understand before engaging, most casinos are known rip customers off through all this bonuses, and only by the rules can we know which bonus to accept and which to avoid.
