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.
xxMikexx [17]
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

Presley needs to have 712 books ready.
