We can use cross-multiplication to set up a proportion:
66/total number of deer = 17/100
Simplifying, we can write:
total number of deer = (66 x 100)/17
total number of deer = 388.24
Rounded to the nearest whole number, the estimated actual number of deer in the forest is 389, which is answer choice D.
