Most of the time it is quite difficult to separate the three functions of money. Money performs its three functions at all times, but sometimes we can stress one in particular. For each of the following situations, identify which function of money is emphasized: a) Brooke accepts money in exchange for performing her daily tasks at her office, since she knowsshe can use that money to buy goods and services: medium of exchange
