Marginal Utility (MU) is the additional utility derived from consuming an additional unit of the good. To calculate MU, we need to find the change in total utility (TU) when one more unit is consumed. 
MU of consuming the first unit = Change in TU / Change in quantity consumed = TU of 1 unit - TU of 0 units = 30 - 0 = 30. 
Therefore, the marginal utility of consuming the first unit is 30. 
The best choice is to consume at least one unit of the good because it provides positive marginal utility.
