Alyssa is trying to decide where to spend this year's vacation. She could go snorkeling in the *Sea of Tranquility on the Moon or she could go skiing on *Mount Olympus on Mars. With the price of fuel, she is wondering how much she will save by traveling to the Moon instead of Mars. Round trip to Mars ( ) is km, but round trip to the Moon ( ) is only km. Her car gets km/L of fuel. At a cost of per liter of fuel, how much will she save by going snorkeling instead of skiing? Convert and to scientific notation before listing them in the Given. *(Note to student: We fully realize that there is no water in the Sea of Tranquility and there is no snow on Mount Olympus. We also realize that no car getskm/L of fuel and that you cannot drive to either Mars or the Moon. However, by the time you read this, fuel might costper liter!) First convert each distance to scientific notation:
