A driver starts a trip with 30 gallons of gasoline in the tank of his car. The car burns 4 gallons for every 80 miles. Assuming that the amount of gasoline in t

Question

G = 30 – (4/80) * d
G = 25 – (5/100) * d
G = 4 – (30/80) * d
G = 80 – (4/30) * d

Answer 1

G = 30 – (4/80) * d  rather strange, I would have written

G = 30 - 4(d/80)      calculate distance, then multiply by gallons
