Presley is organizing the school book sale. Each stall will have 40 books on the shelf and 2 boxes of books with b books inside.
Presley also has 200 books in inventory to refill the shelves as books sell. This situation can be written as the following expression: 40s + (2b)s + 200
How many books should Presley have ready if she plans to open 8 stalls and have 12 books in each box?
Okay, I think your saying he has 200 total right, if so then you will say 200-20 over 2, so 180 divided by two = 80 in each box; now- 40s +(2b)s +200 b=12 and s=8 so; 40x8+(2x12)8 + 200 320 +192 +200 712
