a 12.0 gallon gasoline tank holds 66.0 pounds of gasoline. If this gasoline cost $3.50/gallon, what is the cost of 1 gram of gasoline..
I need help with just the set up part.. I don't know where to start.. help please
you want to find $/g. So, start working with the units:
12.0gal/66lb * 3.50 $/gal * 1lb/454g = $0.0014/g or .14¢/g
