Answer:
absolute on grain: neither, both produce 10
comparative grain: Italy as renounce to less tonds of dates: 0.5 to 2.5
absolute dates: Niger 25 to 5
comparative dates: Niger as it cost 0.4 tonds of grain to produce 1 ton of dates.
Explanation:
For the absolute, we will check which yield the better number.
Fot the comparative, we will check the opportunity cost:
output/potential output of another product
opp cost grain in Italy: 5/10 = 0.5 tons of dates
opp cost grain in Niger: 25/10 = 2.5 tonds of dates
opp cost dates in Italy: 10/5 = 2 tonds of grain
opp cost dates in Niger 10/25 = 0.4 tonds of grain
