Every decision has an Opportunity Cost due to the nature of scarcity, there is always a better alternative not chosen, therefore, there is always an opportunity cost. “The opportunity cost of an alternative is what you give up to pursue it” (Froeb, McCann,Shor & Ward, 2016). When you go to a Maroon 5 concert, you give up $100 of benefits you would have received if you had gone to a Beyoncé concert. Also, you would also avoid $80 of cost for the Beyoncé concert. According to the definition below, the opportunity cost of seeing Maroon 5 concert is $100 - $80 = $20.  Please delve into the statement there are always opportunity costs.  How can an individual make the best decision?  Is there a best decision?  Would one miss an opportunity not attending one of the concerts? Include a minimum of one reference.
