Three colonies of insects were each treated with a different pesticide
over an 8-week period to test the effectiveness of the three pesticides.
Colonies A, B, and C were treated with Pesticides A, B, and C,
respectively. Each pesticide was applied every 2 weeks to one of the
three colonies over the 8-week period. The bar graph above shows the
insect counts for each of the three colonies 0, 2, 4, 6, and 8 weeks after
initial treatment.
Of the following, which is closest to the ratio of the total number of
insects in all three colonies in week 8 to the total number of insects at
the time of initial treatment?
A. 2 to 5
B.
1 to 4
C.
