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 ( d1d1 ) is 122122 km, but round trip to the moon ( d2d2 ) is only 812000812000 km. her car gets 1.54×1031.54×103 km/l of fuel. at a cost of $3.23×102$3.23×102 per liter of fuel, how much will she save by going snorkeling instead of skiing? convert d1d1 and d2d2 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 gets1.54×1031.54×103km/l of fuel and that you cannot drive to either mars or the moon. however, by the time you read this, fuel might cost$3.23×102$3.23×102per liter! )

first convert each distance to scientific notation:

given: d1=.
fuel rate =/l
cost of fuel=/l
