. In 1979 approximately 1/3 of the 37.3 million airline passengers traveling to or from the United States used Kennedy Airport. If the number of such passengers that used Miami Airport was 1/2 the number that used Kennedy Airport and 4 times the number that used Logan Airport, approximately how many millions of these passengers used Logan Airport that year?
(A) 18.6
(B) 9.3
(C) 6.2
(D)3.1
(E)1.6

Please let me know how to solve the problem.

Thanks!

let L b the number who used the logan airport
those using miami airport = 1/2*1/3*37.3

1/2*1/3*37.3 = 4L

solve for L=1.6
