Answer 1

your question implies that there are various choices, from which you must choose; you should include them so that the tutors can explain why one of them is the correct answer!

 

Total cost = ($1.55 per lb)(number of lbs)   is the basic concept.

Answer 2

Unfortunately, we can't see the list of equations from which you may select. However, if we let x = the price for 3.5 lb of grapes, then we can set up the following equation:

 

1/1.55 = 3.5/x
