Suppose an american worker can make 50 pairs of gloves or grow 300 radishes per day. on the other hand, a bangladeshi worker can produce 100 pairs of gloves or grow 200 radishes per day. the opportunity cost of one pair of gloves is:
a) lower for the united states than bangladesh, therefore the united states has a comparative advantage in glove production.
b) the same for both the united states and bangladesh, therefore they both have the comparative advantage in glove production.
c) the same for both the united states and bangladesh, therefore no comparative advantage exists.
d) higher for the united states than bangladesh, therefore the united states has a comparative advantage in radish production.

Jenny​ walters, who owns a real estate​ agency, bought an old house to use as her business office. she found that the ceiling was poorly insulated and that the heat loss could be cut significantly if six inches of foam insulation were installed. she estimated that with the​ insulation, she could cut the heating bill by​ $80 per month and the​ air-conditioning cost by​ $70 per month. assuming that the summer season is three months​ (june, july, and​ august) of the year and that the winter season is another three months​ (december, january, and​ february) of the​ year, how much can jenny spend on insulation if she expects to keep the property for five​ years? assume that neither heating nor​ air-conditioning would be required during the fall and spring seasons. if she decides to install the​ insulation, it will be done at the beginning of may.​ jenny's interest rate is​ 6% compounded monthly.
