23 is the minimum because 155 does not go into evenly and you have to have enough room for everybody, and make sure not to leave anybody out. 155 divided by 7 is 22.1428571429, you have to round it up to 23 so that everybody has a seat. Hope it helps!!

You have no answer unless there is another choice.
(josue) 16.8/7 = $2.4 per lb
(ricardo) 12.75/5 = $2.55 per lb

Answer:
Step-by-step explanation:
and it's an arithmetic sequence.
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
