Q: total count of bag is 5x 150= 750 bags?

Negative. 5x30 = 150. Just an FYI though, if you are using the normal rolls of bags from Target or Walmart and putting heavy stuff in them, these will go twice as far. They don't fall apart.

Q: My main reason is, are they biodegradable?

Per Florid, these bags are recyclable. As to biodegradability, LDPE #4 indicates that LDPE has been combined with a special additive which assist in degradation. From website plasticsrecycling(dot)org: Ask producers of bio-degradable and oxy-degradable plastics additives to prove that their material does what it claims and is safe to recycle. Ask for proof that carpets and geotextiles from recycled PET and highway culvert pipes from recycled HDPE will have their full expected service life if the degradable additives are present in the plastic. Ask if the appropriate APR test protocols have been met. If you are part of a university or industry setting where you can control purchases, work with recyclers to be sure that a material is recyclable before it is introduced for sale in your facility. Talk to your markets to be sure you know what they want and do not want in the bales of postconsumer plastics.

Q: Are these bags dark or see thru?

These bags are not see through, they're black and very strong. I used them for cat litter and they hold quite a bit. I'm buying these from now on, I highly recommend these!
