Question

Assume the top three sources of oil imports for the United States in the same year were Saudi Arabia, Mexico, and Canada. These top three countries accounted for 38% of oil imports. The United States imported 1.2% more from Saudi Arabia than they did from Mexico, and 1.1% more from Saudi Arabia than they did from Canada. What percentage of the United States oil imports was from each country?

Answer 1

s+m+c= 38

s=m+1.2

s=c+1.1

c= s-1.1=m+.1

m+1.2+m+m+.1=38

3m= 36.7

m=36.7/3=12.2333...% from mexico

s=13.4333...% from saudi arabia

c=12.333...% from canada
