She Leaves Some Of These Standard Boxes Empty, And In All The Other Standard Boxes She Puts 8 (empty) Small Boxes. Now, 102 Of All The Boxes On The Table Are Empty. How Many Boxes Has Barbara Used In Total?
Answer» By putting 8 BOXES in a box, the total number of empty boxes INCREASES by 8 - 1 = 7. If we call X the number of times that 8 boxes have been PUT in a box, we know that 11 + 7x = 102. It follows that x=13. In total, 11 + 13 × 8 = 115 boxes have been used. By putting 8 boxes in a box, the total number of empty boxes increases by 8 - 1 = 7. If we call x the number of times that 8 boxes have been put in a box, we know that 11 + 7x = 102. It follows that x=13. In total, 11 + 13 × 8 = 115 boxes have been used.
