Best ResponseYou've already chosen the best response.1The first thing that we need to do there is to figure out how much fuel the car will use on its journey. We're told that the car will cover 32 miles per gallon of fuel used: \[32 miles = 1 gallon\] That mans that: \[1 mile = \frac{ 1 }{ 32}gallons\] Our trip is 384 miles, so: \[384 miles = (\frac{ 1 }{ 32 })(384)gallons\] which I'll let you work out for yourself. So, given that we know how many gallons of fuel will be used, and we're assuming that the 15 gallon fuel tank is full at the start of the journey, we can subtract our fuel usage from 15 to find our how much will be left in the tank upon arrival. \[FuelRemaining = 15 gallons  ((\frac{ 1 }{ 32 })(384))gallons\]

Best ResponseYou've already chosen the best response.0The answer is we don't know because we were not told how much gas was in the tank. If we assume the tank was full with 15 gallons of gas, then do this: \(\dfrac{384~miles}{32 \frac{miles}{gallon} } = \_\_\_\_~ gallons\) \(15~gallons  \_\_\_\_ ~gallons = your ~answer\)
