From 1984 to 1987, the value of
foreign goods consumed annually in
the United States increased by what
percent?
(1) In 1984 the value of foreign goods
consumed constituted 19.8
percent of the total value of goods
consumed in the United States
that year.
(2) In 1987 the value of foreign goods
consumed constituted 22.7
percent of the total value of goods
consumed in the United States
that year.

OA is E
I think the OA shouldbe C.
Can someone explain why it should be E

It should be E..

x= total value of goods consumed in 1984
y= total value of goods consumed in 1987


% increase in foreign goods from (1984 to 87)= ( 0.227 y- 0.198x)/(0.198x) * 100

you don't know the values of x and y.

insuffcient.

You might be thinking that x=y (that is wrong)...
