can someone please help me out with the below problem

It takes Amy between 6 and 7 minutes to grill a steak, and she can only grill one steak at a time. She does not need to take breaks between steaks. Can Amy finish grilling all the steaks needed for her party before her guests arrive?

(1) Amy needs to grill four steaks for her party.

(2) Amy's guests will arrive in half an hour

I am having trouble on the Both statements TOGETHER are sufficient, but NEITHER one ALONE logic. It says this is incorrect because:

(1) AND (2) SUFFICIENT: Amy will take between 24 and 28 minutes to grill the steaks and her guests will arrive in between 25 and 30 minutes, so we cannot answer the question definitively

** in the problem, it says her guests will arrve in 30min. It dont see where it says they will arrive between 25 and 30min.**

any help would be appreciated. Thanks

I was wrong (doing too many problems I think :D took 1st statement also in to consideration when evaluting 2nd which is WRONG )

Is E) the answer since it says in 1/2 hours we dont know if its 29 minutes (yes she would have finsihed by then) or 27 minutes (seh woudl not have finished making steaks then)

so when it says guests will arrive in 30min it doesnt mean exactly 30min. It could be anytime up to 30min, corect?

If I say in 20 minutes I could be there in 15 I think this is saying the something along these lines.

If the question said after 30 minutes then it might have been C)
