Problem

For a point-of-sale total charged in \(\text{dollars}~\text{and}~\text{cents}\), determine the appropriate precision from \(\text{nearest}~\text{cent}\), \(\text{nearest}~\text{meter}\), or \(\text{nearest}~\text{million}~\text{dollars}\). State the dimension match and how it meets the charging requirement.

Answer choices

Choose your path.

Preview only

selected precision = nearest cent; dimension match = money; requirement match = selected only because smallest units are assumed best, without applying the stated policy

selected precision = nearest meter; dimension match = length rather than money; requirement match = this cannot express a point-of-sale total

selected precision = nearest cent; dimension match = money; requirement match = point-of-sale totals use 0.01-dollar increments

selected precision = nearest million dollars; dimension match = money; requirement match = the resolution is unusable for dollars-and-cents charging
