我首先不懂得,就是the average of 100 units of Country R's currency ,這個是怎樣阿?? 雖然最後是問說以這玩意為單位~可是我算出的是5.不過錯了~

頂一下~~我也看不懂這一題

100 units of Country R's currency
應該就是指該國貨幣100元幣值
就是100塊的意思吧??
我理解題目的意思是
add A to the average of B and C
把A=0.02I加上B=100和C=0.01I的平均
0.02I+(100+0.01I)/2=[b]50+5I/40[/b]
不知是C少了一個0還是我的理解有誤呢???
再有人幫忙檢查一下或是修正~~

C:50 + I/40 你的理解是對低～～ 這題我一開始也是霧薩薩～
