Hi

Let x represent how many boxes of cereal can it fill per hour

Question sets up the proportion***

 %285145%2F.7%29+=+%28x%2F1%29  |cross multiplying to solve for x

        .7x = 5145

          x = 7350, boxes of cereal that can be filled per hour



Let x represent long it would take them to deliver 145 papers

 %28100%2F2%29+=+%28145%2Fx%29  |cross multiplying to solve for x
