I got the information filled up out. but i am down to last question i am struggling with.

last bottom question asking me to calcaulate the totals using the datasets. but my concern is, i don't think it is just add them up and done. can you show me how i was supposed to total up on this? just add up total per county such as

USA- $23 plus 15.18 equal 38.18

same thing with other 2 countries.

unless i was supposed to do something else as well?
