+275 3 =117-33 = 29.33 4 c. CHALLENGE PROBLEM: Unfortunately, right before the trip you come down with a case of the Heebie-Geebies. Luckily your Nana has a sure-fire cure: she gives you an eyedropper bottle with the label: "Take 10 drops per 15 lb. body weight per dose four times a day until the geebies subside. Contains 8g heebie bark per 100 drops solution. 64 drops = 1 tsp." If you weigh 128 lbs. and the 4-oz bottle is just under half-full are you at risk of running out of granny's geebie-tonic before the end of the trip?
