Scientists collected fallen acorns that each housed a colony of the ant species P. ohioensis and analyzed each colony's structure. For any of these colonies, if the colony has x worker ants, the equation \( y=0.67x+2.6 \) , where \( 20\le x\le110 \) , gives the predicted number of larvae, y, in the colony. If one of these colonies has 39 worker ants, which of the following is closest to the predicted number of larvae in the colony?
