An economics student recorded the amount of per-capita aid that the U.S. gave to various countries during the 19000s
Blue 1970
Pink 1980
Tunisla Blue ($20)
Tunisla Pink ($35)
Libya Blue ($5)
Libya Pink ($5)
Algeria Blue ($10)
Algeria Pink ($10)
This data is a bit confusing as it is not clear which amounts correspond to the per-capita aid given by the U.S. to each country in the 1970s and 1980s. However, based on the information provided, it appears that the per-capita aid given to each country remained the same between the Blue and Pink years (e.g. Algeria received $10 per capita aid in both 1970 and 1980).
Please provide more specific information or clarify the data so that a more accurate analysis can be done.
