The table shows healthcare spending per capita in a group of African nations. Based on this information, which of the following countries had the greatest change in dollars spent per capita from 2013 to 2015?
A. Eritrea
B. Sudan
C. Tanzania
D. Kenya
To find a solution to this, we need to find the change in spending between the year 2013 and 2015 for each country. Change is difference in amount spent in 2015 and 2013 for each country:
Sudan=$(24-17)= $7
Eritrea=$(42-56)= - $14
Nigeria = $(21-16)= $5
Tanzania =$(81-68) = $13
Rwanda = $(24-27) =-$3
Kenya = $(88-81) = $8
A Minus sign means a decrease in spending. From the above calculations, Eritrea had the GREATEST change in dollars spent while Rwanda had the LEAST change in dollars spent.
Therefore, the Correct Answer is A.
