(1) You & 3 friends decide to “road-trip” to San Francisco for a 3-day weekend. It’s about 320 miles round-trip (mi./trip) and your psychedelic VW bus gets 15-mpg (mi./gal.). With gas at about $2.75 per gallon (dollars/gal.), how much gas money should each of you bring (dollars/person)? (2) 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? Support your answer with calculations. Note: 3 teaspoons = 1 tablespoon and 2 tablespoons = 1 ounce.
