Megan consumed 3.5 gallons of water in one day. how many milliliters are equal to 3.5 gallons, if 1 liter = 1,000 milliliters and 1 gallon = 3.785 liters? a 1,324.75 milliliters b 13,247.5 milliliters c 132,475 milliliters d 1,324,750 milliliters

1 gallon = 3.785 liters

 3.5 * 3.785 = 13.2475 total liters

1 liter = 1000 milliliters

13.2475 * 1000 = 13,247.5 milliliters

 Answer is B

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
