Estimate sums, products, quotients, and percent results, then judge whether an exact answer is reasonable.

Use estimation to choose the best answer

Problem

A baker uses \(5.8~\text{cups}\) of flour in each of \(7~\text{batches}\). Use \(5~\times~7\) and \(6~\times~7\) as bounds to determine the most reasonable proposed total from \(4.06\), \(40.6\), \(406\), and \(42.8~\text{cups}\). Give a complete inequality with the proposed total between the two bounds.
